Abstract:
Frequency-invariant beam patterns are often required by systems using an array of sensors to process broadband signals. In some experimental conditions (small devices for underwater acoustic communication), the array spatial aperture is shorter than the involved wavelengths. In these conditions, superdirective beamforming is essential for an efficient system. We present a comparison between two methods that deal with a data-independent beamformer based on a filter-and-sum structure. Both methods (the first one numerical, the second one analytic) formulate a mathematical convex minimization problem, in which the variables to be optimized are the filters coefficients or frequency responses. The goal of the optimization is to obtain a frequency invariant superdirective beamforming with a tunable tradeoff between directivity and frequency-invariance. We compare pros and cons of both methods measured through quantitative metrics to wrap up conclusions and further proposed investigations.

Abstract:
In some antenna applications, having high directivity while keeping the antenna dimensions small is desired, which can be obtained by use of superdirective arrays. Superdirective arrays have been popular in academic world since a superdirective array provides higher directivity than the uniformly excited antenna array of same length. In this thesis, superdirective arrays are investigated by making high precision numerical computations. Superdirective array element excitations, array factors and directivities are inspected for different number of elements. Superdirective array pattern and directivity features are compared to uniformly excited array pattern and directivities. Superdirective array tolerance is investigated by examination of array element excitation sensitivities. Bandwidth of superdirective arrays is also inspected. Multiple Precision Toolbox is used during numerical computations in Matlab.

Abstract:
L’évolution des standards de communication impose le besoin des architectures antennaires plus sophistiqués associés à des techniques de diversité d’antennes et de formation de faisceaux. Ce type d’antennes offre des nouvelles possibilités pour les applications sans fil en termes d’efficacité spectrale, de fiabilité des liens radio, de réduction de l’impact environnementale ainsi que l’accroissement des capacités des systèmes de communications. Cependant, les techniques conventionnelles de formation de faisceaux entraînent souvent une augmentation significative de la taille de l’antenne. Par conséquent, l’intégration de tel système dans des petits appareils sans fil est relativement limitée. Les réseaux d’antennes compactes et superdirectifs constituent une solution innovante et attrayante pour surmonter ces problèmes. Néanmoins, ils présentent nombreux inconvénients notamment une faible efficacité de rayonnement, un très faible gain et une bande passante très étroite. Ces inconvénients limitent l'utilité des réseaux superdirectifs pour répondre aux besoins des technologies sans fil de nouvelles générations. Dans cette thèse, nous proposons de nouvelles méthodes d’optimisation multi-objectif, basées sur la théorie des modes caractéristiques (NCM), la théorie du facteur de réseau ainsi que les réseaux de neurones artificiels (RNA) pour la conception et le développement de nouvelles architectures antennaires compactes, superdirectives, efficaces et large bande pour des applications 5G
The evolution of wireless communication impose the need for more sophisticated antenna architectures, combined with antenna diversity and beamforming techniques. This type of antenna offers new possibilities for wireless applications in terms of spectral efficiency, radio link reliability, reduced environmental impact and increased communications system capacity. However, conventional beamforming techniques often lead to a significant increase in antenna size. As a result, the integration of such systems into small wireless devices is relatively limited. Compact, superdirective antenna arrays offer an innovative and attractive solution for both beamforming needs and integration in small volumes. However, they exhibits multiple drawbacks, including low radiation efficiency, low gain and narrow bandwidth. These drawbacks limit the usefulness of superdirective arrays to meet the needs of new-generation wireless technologies. In this thesis, we propose new multi-objectives optimization methods, based on network characteristic mode theory (NCM), array factor theory as well as artificial neural networks (ANN), for the design and the development of new compact, superdirective, efficient and wideband antenna architectures for 5G applications

Abstract:
Radio astronomy is used to study stars, galaxies, black holes and gas clouds radiation at radio frequencies. Detecting extremely weak signals from deep space radio sources requires high sensitive feed system associated with large dish antennas. The key figure of merit is survey speed, or the time required to map a region of the sky to a given source flux density. Survey speed is proportional to the frequency bandwidth, the field of view or observable region of the sky, and the squared sensitivity, where sensitivity is related to reflector aperture efficiency and system noise temperature. Compared to the traditional single feed, phased array feeds with significantly expanded field of view are considered as the next generation feed for radio telescope. This dissertation outlines the design, analysis and measurement of high sensitivity L-band and mm-wave phased array feeds for the 100-meter Green Bank Telescope. Theoretical works for radio astronomy includes design guideline for high sensitivity phased array feed, fundamental frequency bandwidth limit, array antenna loss influenced by mutual coupling and beamformer coefficients and possibility of superdirectivity for radio telescopes and other antennas. These study are helpful to understand and guide the design of a phased array feed system. In the absence of dish antennas, sparse phased arrays with aperiodic structure have been developed for satellite communications. A compromise between the peak side lobe level, array element density, directivity and design complexity is studied. We have found that the array peak side lobe level can be reduced by enhancing the array element direction at the main lobe direction, increasing the array element density and enlarging the array size. A Poynting streamline approach develops to understand the properties of a receiving antenna and the mutual coupling effects between array elements. This method has been successfully used to generate effective area shape for many types of antennas and guide the design of a superdirective antenna. Motivated by this method, a superdirective antenna is experimental demonstrated.

Abstract:
This thesis presents a comparative analysis of baseline microphone array speech enhancement techniques that are prominent in current literature. Delay-sum beamforming, sub-array beamforming, near- and far-field superdirectivity, the generalised sidelobe canceller and the adaptive system for microphone-array noise reduction (AivINOR) are evaluated in varying noise conditions and for different array geometries. The effect of complementing each technique with a postfilter is also assessed. A novel beamformer, termed the near-field adaptive beamformer (NFAB), is introduced and then shown to provide superior enhancement performance over any of the baseline techniques assessed. A description of the design and implementation of a high-speed, multi-channel speech data acquisition system is also presented.

Abstract:
Cette thèse a pour objectif l’étude et la recherche d’amélioration de la technologie d’antenne réseau superdirective. Cette technologie a récemment été rééxaminée dans la littérature car elle peut apporter des fonctionnalités intéressantes pour les applications de télécommunication futures. L’examen de ce type d’antenne est donc conduit à travers l’outil de la décomposition en ondes sphériques qui permet l’étude générale des limites de directivité ou de gain, en considérant des pertes d’énergie dans l’antenne. La théorie classique des antennes réseau end-fire est aussi revue, dans le cas de réseaux à espace inter-éléments uniformes et à éléments indépendamments excités. Cette étude fournit une évaluation analytique de l’efficacité et de la sensibilité à la précision des coefficients d’excitation.Les dipôles infinitésimaux et les sources de Huygens sont considérés dans une proposition de développement qui lie la théorie des réseau et de la décomposition en ondes sphériques. Cette contribution fournit une preuve formelle de la limite de directivité des réseaux end-fire de sources de Huygens ainsi qu’une borne supérieure de la directivité des réseaux de dipôles, quand la distance inter-éléments tend vers zéro.. De plus, il est montré comment la théorie classique des antennes réseau peut aussi être utilisée pour extraire des coefficients d’excitations qui maximisent le gain plutôt que la directivité, quand des résistances de pertes sont considérées. Un examen est aussi fait selon la taille d’antenne pour montrer quelles conditions sont les plus favorables pour l’utilisation de réseaux end-fire optimisés pour le supergain ou pour la superdirectivité.Dans une seconde partie, les implémentations pratiques d’antennes superdirectives sont revue dans l’état de l’art, en se concentrant sur les sources de Huygens et les réseaux compacts end-fire. L’architecture d’implémentation choisie de réseau à éléments parasites est ensuite détaillée est étudiée dans le but de minimiser le recours à des résistances positives ou négatives. Cela mène à la conception et aux mesures de cinq prototypes qui visent à atteindre le maximum de gain ou de directivité possible, pour une taille d’antenne limitée, avec des réseaux end-fire de deux, trois et quatre dipôles
The purpose of this thesis is to study and seek improvement of the superdirective antenna array technology. This technology has been recently re-examined in the literature since it can bring some interesting functionalities in the future telecommunication applications. The examination of this type of antenna is thus conducted through the use of Spherical Wave Expansion which allows for the general study of directivity limits as well as gain limits, considering lossy antennas. The classical theory of end-fire array antennas is also reviewed, in the case of uniformly spaced tapered arrays, providing theoretical evaluation of efficiency and sensitivity to source feeding precision.Infinitesimal dipoles and Huygens sources are considered in a proposed development that links array theory and Spherical Wave Expansion. This contribution provides a formal proof for the directivity limit of Huygens-source-based end-fire arrays as well as an upper bound for the directivity of dipole-based arrays, when the inter-element spacing tends to zero. Moreover, it is shown how classical array theory can also be used to derive excitation coefficients that maximize gain rather than directivity, when loss resistances are considered. An examination over antenna size is also made to demonstrate which conditions are most favorable for the use of such supergain or superdirective end-fire array optimization.In a second part, practical implementations of superdirective antennas are surveyed, focusing on Huygens sources and compact end-fire array designs. The chosen implementation architecture of parasitic element arrays is then detailed and studied, in order to minimize the requirement for negative or positive resistive loads. This lead to the design and measurement of five prototypes that aim at achieving the maximum possible gain or directivity for a limited radiator size, with two-, three- and four-dipole end-fire arrays

Abstract:
Base station antennas for next generation mobile communication networks will be required to have a wide bandwidth for compatibility and support multi-beam applications. Antenna arrays are one possible candidate for a next generation base station antenna since they can obtain high directivity, support multi-beam and wide angle scanning. However, a wide-band antenna array faces several problems at the low frequency limit. The electrical size of the antenna array becomes smaller at the low frequency and it becomes harder to obtain high directivity. Another issue is that the bandwidth becomes narrower for electrically small antenna arrays under superdirectivity constraints. The Q-factor is a measure of losses and is proportional to the ratio of the stored energy to the dissipated power. It is also inversely proportional to the fractional bandwidth of an antenna array when Q ≫ 1. In this thesis, we investigate the relation between the Q-factor and the directivity and extend our analysis to a superdirective antenna array. The model we are using is based on the antenna designed for base station applications with the frequency range from 700MHz to 4.2GHz and we assume that it is placed over an infinite ground plane. We calculate the Q-factor at 745MHz, which is the center frequency of GSM 700MHz bands using convex optimization. Here, we use the CVX as the convex optimization tool, which can be easily integrated with MATLAB. The expressions of the stored energy and the radiated power are formulated in a matrix form based on the Method of Moment (MoM) using Rao-Wilton-Gilson (RWG) basis functions for the convex optimization. We show the trade-off between the directivity and the Q-factor, or the bandwidth at the low frequency limit. The results are investigated forth cases; one is a vertical model, where each array elements is placed vertically above an infinite ground plane, and the other is a horizontal model, where each array elements is placed horizontally. We show that the Q-factor is slightly lower for the vertical case than the horizontal case.
Nästa generations basstationsantenner för kommunikationsnätverk förväntas hantera flera frekvensband och en metod för detta är att de har stor bandbredd, de förväntas också stödja funktionalitet för multi-beam tillämpningar. Gruppantenner är en möjlig kandidat som både kan erbjuda hög riktverkan hos fjärrfältet, och som har multi-beam kapacitet och möjligheter till vidvinkelscanning. Sådana bredbandiga gruppantenner blir elektriskt små i deras lågfrekvensgräns, och detta ger flera utmaningar på deras funktionalitet för låga frekvenser. Sådana utmaningar är bland annat att få hög riktverkan i deras fjärrfält vid de låga frekvenserna. Strömmar på en elektriskt liten antenn som genererar hög direktivitet (riktverkan) har liten bandbredd, dvs strömmen på den givna geometrin måste förändras mycket som funktion av frekvensen för att bibehålla hög direktiviteten. Q-faktorn är ett mått på förhållandet mellan den upplagrade energin genom den utstrålade effekten. Den år också omvänt proportionell mot den relativa bandbredden när Q ≫ 1. I denna avhandling undersöker vi sambandet mellan Q-faktorn och diriktiviteten hos två konfigurationer av gruppantennelement framförallt med avseende på superdirektiva gruppantenner. Utifrån en existerande experimentell gruppantenn designad för basstationsapplikationer med start frän 700 MHz upp till 4.2 GHz skapar vi två ideala modeller dar vi antar att gruppantennens element är placerad över ett oändligt jordplan. Vi beräknar den lägsta Q-faktorn för den givna geometrin och given direktivitet vid 745 MHz, vilket är mittfrekvensen för GSM 700 MHz-banden med hjälp av konvex optimering. Här använder vi CVX som den konvexa optimeringsverktyg, som är integrerad med MATLAB. Uttrycken av den upplagrade energin och utstrålad effekt formuleras i en matrisform med hjälp av Metod Moment (MoM) uttryckt med Rao-Wilton-Gilson (RWG) basfunktioner. Denna matris-baserade representation av storheterna blir input till en konvex optimering. Vi best¨ammer en relation mellan direktivitet och Q-faktorn, för dessa geometrier. Detta kan formuleras om som bandbredden vi lågfrekvensgränsen hos gruppantennen.

Abstract:
This thesis deals with the problem of synthesizing planar, maximally sparse, steerable and non-superdirective array antennas by means of convex optimization algorithms and testing their performances on an existing array to assess its far field performances in terms of requirements ful- filment. The reason behind the choice of such topic is related to those applications wherein the power supply/consumption, the weight and the hardware/software complexity of the whole radiating system have a strong impact on the overall cost. On the other hand, the reduction of the number of elements has of course drawbacks as well (loss in directivity, which means a smaller radar coverage in radar applications, loss in robustness, etc.), however the developed algorithms can be utilized for finding acceptable trade-offs that arise, inevitably, when placing advantages and disadvantages of sparsification on the balance: it is only a matter of appropriately translating requirements in a convex way. The synthesis scheme will be described in detail in its generality at the beginning, showing how the proposed synthesis techniques outperform several results existing in literature and setting the bar for new benchmarks. In particular, an important, innovative constraint has been considered in the synthesis problem that prevents selection of elements at distances below half-wavelength: the non-superdirectivity. Moreover, an interesting result will be derived and discussed: the trend of the reduction of the number of elements Versus the (maximum) antenna size is decreasing as the latter increases. Afterwards the discussion will be focused on an existing antenna for radar applications, showing how the proposed algorithms intrinsically return a single layout that works jointly for transmitting and receiving (two-way synthesis). The results for the specific case chosen (mainly the set of weights and relative posi- tions) are first numerically validated by a full-wave software (Ansys HFSS) and then experimentally assessed in anechoic chamber through measurements.

There are two topics in this thesis: one is supersensitive sound pickup and the other is super directive microphone array with application in nearfield acoustic holography. The former contains horn and curved array, and we will discuss the theory, design method and the result. Final, the device is applied to the application in a distant recording. Conventional nearfield acoustical holography (NAH) is generally based on the free-field assumption, which can cause errors when interfering sources are present in practical environment. Although the measurement of particle velocity as the input to NAH provides certain advantage, the noise problem of finite difference estimation of particle velocity can nullify the velocity-based reconstruction that is better conditioned than the pressure-based process. Alternatively, this paper examines the feasibility of using directional sensors in each channel of the microphone array such that the robustness of inverse reconstruction is enhanced against reflections from boundaries. With two microphones in each channel, the directivity of each array element is tailored according to various design criteria of first-order differential microphones. Directivity index, front-to-back ratio and constant beam-width are employed as the objective functions for optimizing array filters. The proposed methods are utilized in an Equivalent Source Model (ESM)-based NAH. The proposed techniques are verified by numerical simulations and experiments, with interfering source positioned at various directions. Sound field is reconstructed using the pressure input and the particle velocity estimated by the finite difference method.
