Résumé :
In this paper we study microstrips with rectangular and rounded edge cross sections. A hybrid quasistatic method is applied and the effective permittivity and the attenuation constant of the microstrip are found. Instead of the dielectric constant of the substrate an ideational one is used that depends on the geometry and the frequency. The attenuation constant for the rectangular microstrip was found to be in good agreement with values given in the literature. A microstrip with a rounded edge cross section has a smaller attenuation constant due to the conductor than that of a microstrip with a rectangular crosssection. Thus, a rounded edge microstrip is preferred because it will give an appreciable effect in reducing the ohmic losses of the line.

Résumé :
Abstract In this paper, a circularly polarized (CP) low cost, low profile antenna with broadband stable gain is proposed. The antenna consists of a grounded square slot with two inverted-L shaped microstrips, an asymmetrical Y-shaped microstrip radiator with a stub, and several fine tuning elements. The CP radiation is first realized by using the Y-shaped microstrip line, which incorporates a stub is to realize better impedance matching. Next, by utilizing two Inverted-L microstrips into the corners of the grounded slot, the axial ratio (AR) characteristic can be further improved. A wider AR bandwidth (ARBW) can be achieved by utilizing four rectangular strips as fine tuning elements. Simulation results show the proposed antenna demonstrates a radiation with a CP bandwidth of 50% and a stable gain with average value of 5.18 dBi.

Résumé :
In this paper, a wideband bandpass filter with a coupled line cross-shaped resonator (CLCSR) is proposed. The proposed bandpass filter is composed of two open-end parallel coupled lines, one short-end parallel coupled line, one branch microstrip line, and the parallel coupled line feed structure. With the use of the even and odd mode approach, the transmission zeros and transmission poles of the proposed bandpass filter are analyzed. The coupling coefficient of the parallel coupled line feed structure is big, so the distance between the parallel coupled line is too small to be processed. A three microstirp lines coupled structure is used to realize strong coupling and cross coupling. This structure also can reduce the return loss in passband and increase the out-of-band rejection. The transmission zeros can be adjusted easily by varying the lengths of the open-end parallel coupled line or the short-end parallel coupled line. The proposed bandpass filter is fabricated and measured. The simulated results agree well with the measured ones, which shows that the design method is valid.

Résumé :
Microstrip antennas are widely used in people's daily life. Microstrip antenna has the advantages of low cost, low profile, small space occupation, and high conformal capability. So the design of microstrip antennas can be encountered in daily life. Microstrip antennas include the military, aerospace, medical, and so on. Microstrip antenna has a wide research space. The three microstrip antennas, U-shaped open slit laminated microstrip antenna, dual frequency circularly polarized laminated microstrip antenna, and non-radiating edge-fed broadband double-layer microstrip patch antenna are mainly introduced to understand the research progress and expectation of today's microstrip antennas. This paper firstly introduces the basic theoretical concept of microstrip antenna, then introduces the cavity mode theory, and then mainly lists and introduces three kinds of designed microstrip antenna structures. Finally, these three types of microstrip patch antennas are analyzed. And the advantages, disadvantages, and development fields of the corresponding types of microstrip patch antennas are introduced. The application determines the structure of the method used, and each design has its strengths. Microstrip antennas always have room for research, and continuous research will be applied to more fields.

Résumé :
Thesis advisor: Krzysztof Kempa
The resonant modes of a sequence of periodically spaced microstrip resonators is studied. The system is analyzed as transmission line with periodic capacitive gaps, as a waveguide with apertures via normal mode expansion, and through a derivation of the static fields in the gap between two microstrip resonators via conformal mapping. FDTD simulations are also performed to numerically calculate the resonant modes of the sequence and also its absorption spectrum when it contains a lossy dielectric. It is found, as expected, that when the gap size is large, the microstrip resonators are uncoupled and there resonant modes are unperturbed. As the gap size narrows, the resonators become strongly coupled, and changing boundary conditions perturb the resonant modes upwards in frequency. Moreover, an additional resonant mode is observed that does not correspond to any uncoupled mode

Texte intégral
Résumé :
Una línia de transmissió three-line-microstrip consisteix en tres pistes paral·leles practicades sobre la cara d'un dielèctric amb un pla de massa inferior. La propagació en aquesta línia es pot descriure en termes de tres modes fonamentals anomenats ee, oo i oe. Tot i que aquests modes són ortogonals interaccionen entre sí a qualsevol transició, discontinuïtat o asimetria. En el pla d'una transició o asimetria es genera un intercanvi d'energia o conversió modal en el que prenen part tots els modes.
En aquest treball s'analitza la conversió modal que s'origina en un conjunt de transicions i asimetries construïdes sobre línies three-line-microstrip. L'estudi es realitza aplicant la tècnica de l'anàlisi multimodal. L'ús d'aquesta tècnica permet la deducció d'una sèrie de models multimodals (un per a cada transició) que proporcionen una anàlisi simple, rigorosa i quantitativa d'aquest fenomen.
La validesa d'aquest estudi es verifica de manera experimental. Els bons resultats obtinguts demostren que els models multimodals proposats prediuen de manera precisa el comportament de les transicions. Aquest fet permet el seu ús per analitzar circuits o estructures constituïts per trams de tres pistes acoblades. En el cas d'aquesta tesi, han estat aplicats als camps de l'EMC i de les microones. Pel que fa a l'EMC, s'ha realitzat un estudi de l'acoblament i la integritat del senyal en configuracions de PCB amb trams de tres pistes acoblades. Aquest estudi ha permès identificar les transicions i asimetries en aquests circuits com a possibles fonts d'interferència i de degradació dels senyals ja que la conversió modal es pot interpretar com a un procés d'interferència que involucra tots els senyals presents. Pel que fa a les microones, s'ha realitzat una anàlisi multimodal de filtres spurline. Aquesta anàlisi ha permès desenvolupar dues noves estructures, la principal característica de les quals és la seva compacitat que, a diferència d'altres estructures similars, s'aconsegueix permetent la presència d'un nou mode en el procés de ressonància. L'ús dels models multimodals per a l'anàlisi d'aquestes estructures ha permès una interpretació clara i senzilla del seu funcionament així com el desenvolupament d'una sèrie de regles de disseny que permeten un ajust fàcil i ràpid de certs paràmetres dels filtres com ara la freqüència central i l'ample de banda.

En el campo de las microondas, se ha realizado un análisis multimodal de filtros spurline. Este análisis ha permitido desarrollar dos nuevas estructuras, cuya principal característica es su compacidad que, a diferencia de otras estructuras similares, se consigue permitiendo la presencia de un nuevo modo en el proceso de resonancia. El uso de los modelos multimodales para el análisis de estas estructuras ha permitido una interpretación clara i sencilla del su funcionamiento así como el desarrollo de una serie de reglas de diseño que permiten un ajuste fácil i rápido de ciertos parámetros de los filtros como por ejemplo la frecuencia central y el ancho de banda.
A three-line-microstrip transmission line consists of three parallel coupled strips printed on a grounded dielectric substrate. The propagation in this line can be described in terms of three fundamental modes, namely the ee, oo and oe modes. These modes are orthogonal and propagate independently unless a transition or asymmetry is present in the line. Any transition or asymmetry will generate an energy exchange or modal interaction among all the propagating modes.
In this work, the modal interaction of a set of transitions and asymmetries in three-line-microstrip transmission lines is analyzed. The study is carried out by using the multimodal analysis. By means of this technique a set of multimodal circuit models (one for each transition) is derived. These models provide a simple and a quantitative interpretation of the modal interaction.
The proposed multimodal analysis is experimentally validated. The obtained results show that the derived multimodal models accurately predict the behavior of the transitions. Due to this fact, they can be used for the analysis of circuits and structures composed of three-coupled-strip sections. In this work, the models have been applied to both the EMC and microwave fields. In the former, they have been employed to study the cross-talk and signal-integrity problems in PCB configurations involving tree-coupled-trace sections. The performed analysis has shown that transitions and asymmetries in these circuits must be considered as a source of interference and signal degradation since the modal interaction can be interpreted as an interference process that involves all the present signals. In the latter, a multimodal analysis of spurline filters has been performed. This study has allowed the derivation of two new filter structures whose main feature is their compactness, which, in contrast to other analogous filters, is achieved by allowing the presence of an additional mode in the resonance process. The use of the multimodal models for the analysis of these structures has permitted both a simple interpretation of the filter operation and the derivation of a set of design rules which allows a rapid fine tuning of some filter parameters such as the center frequency and the bandwidth.

Résumé :
A model is presented which incorporates the advantages of a mixed mode simulation to characterize transmission line behavior in multiple coupled Transmission line systems. The model is intended for use by digital circuit designers who wish to be able to obtain accurate transmission line behavior for complex digital systems for which continuous time simulation tools such as SPICE would time prohibitive. The model uses a transverse electromagnetic wave approximation to obtain solutions to the basic transmission line equations. A modal analysis technique is used to solve for the attenuation and propagation constants for the transmission lines. Modal analysis done in the frequency domain after a Fast Fourier Transform of the time-domain input signals. Boundary conditions are obtained from the Thevinized transmission line input equivalent circuit and the transmission line output load impedance. The model uses a unique solution queue system that allows n-line coupled transmission lines to be solved without resorting to large order matrix methods or the need to diagonals larger matrices using linear transformations. This solution queue system is based on the method of solution superposition. As a result, the CPU time required for the model is primarily a function of the number of transitions and not the number of lines modeled. Incorporation of the model into event driven circuit simulators such as Network C is discussed. It will be shown that the solution queue methods used in this model make it ideally suited for incorporation into a event-driven simulation network. The model presented in this thesis can be scaled to incorporate direct electromagnetic coupling between first, second, or third lines adjacent to the line transitioning. It is shown that modeling strictly adjacent line coupling is adequate for typical digital technologies. It is shown that the model accurately reproduces the transmission line behavior of systems modeled by previous authors. Example transitions on a 8-line system are reviewed. Finally, future model improvements are discussed.

Résumé :
Abstract In the first part of this study, determination of the dielectric properties of the low loss microwave ceramic material, barium nonatitanate (Ba2Ti9O20), around 1 GHz is discussed. The structures under test were coaxial resonators, the cores of which were made of barium nonatitanate and the metallization was realised by thick film silver. The measured value of the real part of the relative dielectric constant was εr = 37 and that of the loss tangent was tan σ = 0.00014. The change of the resonance frequency of the coaxial resonators with temperature, in the range -20 … +80 C, was 4 ppm/ C. In addition, realisation of compact interdigital and comb-line bandpass filters was demonstrated for the 900 MHz mobile phone band. Besides Ba2Ti9O20, Ba(Sm,Nd)2Ti5O14 ceramic material with a dielectric constant of εr = 78 was also employed in order to improve the miniaturisation. The volume of the smallest filter was 2 cm3 and the weight was 9 g. In the second part of this study, various measurement methods have been demonstrated to determine the real part of the relative permittivity of FR4 fibreglass circuit board. Test structures were straight asymmetric open-circuited strip lines. It was found that the real part of the relative permittivity decreased slightly with frequency. At 0.72 GHz and 4.5 GHz, εr values of 4.3 and 4.1, respectively, were measured. All the characterisation methods used gave consistent values for εr, and electromagnetic simulators were used to verify the results. In the third part of this study, the structures under test were microstrip or strip line transmission lines, the S parameters of which were measured by using on-wafer measurement techniques. It was found that the insertion loss of the 10 mm long etched Cu microstrip was slightly less than that of the Ag microstrips which were manufactured by etching and gravure offset printing techniques, respectively. The performance of the Ag microstrips was, however, similar. In addition, a theoretical basis was established for the determination of εr of the dielectric substrate and the attenuation coefficient of the transmission lines under test. The calculations were based on signal flow diagrams. The method was applied to determine the dielectric and loss properties of a commercial, Kyocera, Japan, LTCC (Low Temperature Cofired Ceramic) material up to 50 GHz. The measured value of the real part of the relative permittivity was εr = 5.7, and the loss tangent was approximately tan σ = 0.003. The essential idea behind the studies reported in this thesis was twofold. First, the studies aimed at characterising dielectric media which find usage in the realisation of UHF, microwave or millimetre wave circuits. Second, the studies aimed to obtain data of immediate value in practical design work. For this reason, the structures under test were transmission lines having extensive usage in practical high frequency circuit design.

Résumé :
Microstrip transmission lines consisting of a narrow center line and an extended groundplane are the most commonly used device interconnections in millimeter-wave integrated circuits. Typically, the ground plane of a microstrip line is located on the backside of the roughly 500 µm thick semiconductor wafer that carries the circuit elements. For frequencies above 10 GHz, this simple scheme can lead to a limitation of the useful bandwidth of ultra-high-speed electronic circuits because dispersion can significantly distort the electrical pulses propagating on the microstrip interconnect [Goossen, 1989]. Recently, it has been proposed to use buried silicide layers as groundplanes for microstrip lines in silicon based circuits [Goossen, 1990]; the resulting reduction in the separation of the center conductor and the ground plane should push the onset of the dispersion to frequencies above the range of interest. For a separation of 10 pm the dispersion should be negligible for frequencies up to 500 GHz. Here, we test this concept by studying the propagation of 100 GHz bandwidth electrical pulses on microstrip lines that have been fabricated on silicon wafers with buried and with conventionally formed groundplanes.

Résumé :
Low Temperature Co-fired Ceramic (LTCC) materials are widely used in ceramic packaging and interconnect applications, such as RF receiving modules for next generation handsets and T/R modules for satellite communications. The application frequency spans from low GHz to 100+ GHz. A variety of techniques must be used to characterize dielectric properties (loss tangent and dielectric constant) of LTCC in the wide frequency range. These techniques include the parallel plate capacitor method from DC to several MHz, cavity methods in x-band, and open resonator techniques for frequencies up to 100+ GHz. LTCC is a multi-layer ceramic technology, which offers capability for low cost manufacturing, realizing 3D structures, and embedding passive components. Both strip line and microstrip types of transmission line structures can be conveniently manufactured using LTCC material systems. As an important performance parameter, microstrip loss can be characterized using the ring resonator technique. Both LTCC and metal conductors contribute to the microstrip loss. At microwave and mm-wave frequencies, metal losses become significant, although low resistance silver conductor can be used. The metal loss may be divided into two categories: one is the resistive loss and other is surface roughness loss. A photo imaging technique has been introduced which patterns the microstrip, reducing the surface loss. In this paper, the techniques for measuring both dielectric properties of A6 LTCC and microstrip properties of A6 LTCC with conductor systems will be reviewed. Characterization results of the dielectric constant and loss tangent of A6 from near DC to 100 GHz will be presented. Microstrip losses, measured for A6 LTCC with both gold and silver metallization up to 40 GHz, are compared to those computed using the closed form equations and experimentally determined dielectric and conductor properties. The calculated effective microstrip permitivity and attenuation compare well to those from measurements.

Résumé :
In this paper, a multi-layer LCP substrate fabrication process was described and millimeter wave transmission lines and filters were designed and fabricated on the LCP substrate. Various transitions from a CPW to a microstrip line with their characteristic impedance being 50 ohms were investigated. The characteristics of the wirebonding assembly for connecting two transmission lines was also examined. The measurement results show that an insertion loss of 1.3 dB at 60 GHz can be achieved for the two-wire bonding trasmisssion line including two transitions from a CPW to a microstrip line.

Résumé :
This paper presents a novel interrogation mechanism for an antenna sensor subjected to high temperatures. In sensor node, an Ultra-wide Band (UWB) microstrip antenna was used as a wireless Tx/Rx transceiver to amplify the reflected interrogation signal from the temperature-sensing element, i.e. the patch antenna-sensor. A microstrip delay line was used to connect the Tx/Rx antenna and the antenna-sensor so that the reflected signal from the sensor node is delayed and can be separated from the background clutter using time-domain (T-D) gating technique. In this paper, the principle of operation of the proposed interrogation mechanism is first discussed, followed by the design and simulations of the sensor node circuitry. Finally, a temperature test was conducted to validate the wireless temperature sensing performance of the antenna sensor.

Résumé :
Frequency tuned IR laser sources can be achieved by generating the upper and the lower sidebands from a CO2 laser using an electrooptic phase modulator. The phase modulator, which is driven by a microwave TWT amplifier in the X and Ku bands (8 to 18 GHz) can be made of either a GaAs IR waveguide with a traveling-wave microstrip transmission line (Ref. 1) or a bulk CdTe crystal filled microwave cavity operating in a resonant mode (Ref. 2). The difference between the two approaches is primarily in the achievable frequency tuning range. With a microstrip IR waveguide modulator, the frequency tuning range of 20 GHz, which is at least 20 times wider than that obtainable with a bulk crystal filled microwave cavity can be achieved. The sideband powers of comparable magnitudes (~ 2mW) can be generated by using either of the above two techniques.

Résumé :
The low conductor loss of superconducting materials makes it possible to build passive microwave devices that cannot be built with normal metal conductors. For example, compact transversal filters in the form of tapped delay lines can be fabricated from superconducting niobium to operate with multi-gigahetz signal processing bandwidths [1,2]. Recent advances in the growth of thin films of the high-temperature superconductor (HTS) Y-Ba-Cu-O [3,4] have made possible the demonstration of a variety of passive microwave devices. This includes long delay lines [5], tapped delay line filters [6], and narrow-band microstrip bandpass filters using edge-coupled resonators [5]. The most notable of these demonstations has been the operation of a 2.6-GHz bandwidth stripline chirp filter with 12 ns of total delay and a Y-Ba-Cu-O patterned line length of 0.7 m. The HTS microwave components crucial to this development were long delay lines with more than 10 ns of delay, impedance transformers, and backward-wave couplers. Microstrip, coplanar, and stripline geometries were all examined during the course of this development. The stripline configuration selected for the chirp filter was developed using microwave CAD routines and superconducting niobium prototypes.

Résumé :
In printed circuit boards (PCB), the selection of surface finish is a balance of cost, performance and material compatibility consideration. When the operating frequency is in gigahertz range, the signal loss in interconnects has stronger dependence on the material composition of traces, surface finishes, substrates, and geometry of the traces. Skin effects, frequency dependent dielectric properties and the electrical functioning mechanism are important factors that affect signal integrity. In this work, both measurements and finite element method (FEM) based full wave simulation are used to investigate the effects of hot air solder leveling (HASL) and its alternatives on signal degradation of high-speed interconnect structures. For the microstrip line structure, the loss due to surface finishes is negligible. For the differential mode coupled microstrip lines, the loss increment resulted from surface finish can be up to 50%∼200% at 10 GHz. Surface finish caused signal loss must be carefully considered for differential mode interconnects.
