Based on the development of 5G, this paper will need to establish a large number of small base stations. Therefore, a circularly polarized antenna with adjustable field mode can be easily realized. The field-type modulation improves the point-to-point communication capability, and the circular polarization improves the ability to resist noise. It is a simple template for the antenna of a small base station in the future. At the antenna end, we propose a new antenna model with simple structure. Under the traditional circular planar antenna, the ring structure is added to maintain the stability of circular polarization, and the change of the capacitive impedance of the passive component makes the peak position of the field easily. At the same time, the antenna still maintains circular polarization; the concept of left and right handed metamaterials is added to the feed network to create a broadband single circular polarization feed network, which can maintain a certain phase difference over a wide range of bandwidths.. The characteristic of the antenna is that the field modulation can be achieved without a large-area phase array, and the direction of the field modulation can be designed in any direction of 360 degrees of the circular planar antenna according to requirements, and because the phase array is not used. The concept makes the field polarization remain circular after the time of the modulation, and the frequency change range is not large before the field modulation and unmodulation, and it will not be like the leakage wave antenna, and the frequency change occurs during the modulation. Not conducive to the application of the actual communication.

In this thesis, we propose two compact CPW-fed printed square slot antennas with wideband and dual-band circular-polarization (CP) operation. The features of the wideband CP slot antenna include an inversed-L-type strip protruding into the slot from a 50 coplanar-waveguide transmission line, a square patch and a metal strip embedded in the slot. This antenna has a 3-dB axial-ratio bandwidths of as large as 32%. To obtain dual-frequency circular-polarization operations, the proposed dual-band CP antenna is constructed with a pair of square-ring back patches and a grounded metal strip. The axial-ratio quality of the two operating bands can be tuned by the width of a signal strip protruded into the square slot from a 50 coplanar-waveguide transmission line and the length of a pair of strips in the diagonal corners of the outer square-ring back patch. The ratio of two frequencies with the best axial-ratio value in two operating band, respectively, can be adjusted within the range 1.18–1.37 by the length of the grounded strip. Detail descriptions on antenna development including starting design idea, original antenna construction and modification procedures are presented.

In this thesis, one circularly polarized (CP) sequential array antennas with broadside radiation patterns of narrow beamwidth is proposed. Which is constructed with a four-element circularly polarized square slot antenna loaded by a notched rectangular patch. Broadband CP operations can be obtained by this type of antenna element. The 3dB axial ratio bandwidth can be improved by dimensions of the notched rectangular patch. In addition to have broadside radiation patterns of narrow beamwidth, experimental results also show that good CP performances can be achieved by constructing sequentially rotated array antennas with properly arranged antenna elements abovementioned of orthogonal direction between them and a properly designed feeding network of 90 degrees phase shift between each feed of antenna elements. The analysis and designed dimensions of the antenna elements and the whole constructions of the sequentially rotated array antennas obtained with the aid of the commercially available simulation software Ansoft HFSS (High-Frequency Structure Simulator) are also discussed and presented in this thesis.

Higher-order mode excitation and circularly polarized radiation are two important applications of coplanar waveguide (CPW) fed circular microstrip antenna. In this thesis, design and analysis for these applications are presented. The experimental procedure and results are also described in detail. For excitation of higher-order modes, we introduce the capacitive and inductive coupled feeding structures. By tuning the dimensions of coupled slot and the feed position, higher order modes that we expected from circular microstrip antenna can be excited successfully. Experimental results show that the far-field radiation patterns of these higher-order modes are satisfactory and are suitable for various wireless communication applications. For radiation of circularly polarized wave, we analyze the mechanism of circularly polarized (CP) radiation by using the equivalent circuit, and discuss some of the CPW-fed CP antennas presented in the literature. We found that the transmittion mode of CPW has a strong interference on the radiator. Thus, the linear resonant mode of this radiator can not be separated into two orthogonal components with perturbed 90° phase difference. Therefore, it is difficult to perform CP radiation by a direct CPW feed. For this reason, we propose a symmetric CPW to slotline feeding structure to overcome this problem and the perturbation is employed to generate CP wave. Moreover, unlike the 90° hybrid configuration in [24], this symmetric feeding structure is convenient for antenna array design and the slotline mode of the CPW can hardly be excited. Finally, we design a series of CPW-fed CP antenna and antenna array by using the above symmetric feeding structure. Experiments have shown all of our designs can radiate good and stable CP waves. This symmetric feeding structure can be applied not only to the circular patch antenna but also to various other shapes of the patch antenna. This indirectly proves the influence of CPW on CP radiation and provides the important consultation for CP antenna design.

Full textThis communication presents a single-feed ultra-wideband circularly polarized (CP) antenna with high front-to-back ratio (FBR). The antenna is composed of two orthogonally placed elliptical dipoles printed on both sides of a substrate. To realize high FBR, a novel composite cavity is also proposed and integrated with the presented crossed dipoles, which effectively reduces the backlobe of the crossed dipoles. Simulation results are in good agreement with the measured results that demonstrate an impedance bandwidth from 0.9 to 2.95 GHz (106.5%) and a 3-dB axial ratio (AR) bandwidth from 1 to 2.87 GHz (96.6%). The measured FBR is about 30 dB across the whole global navigation satellite system (GNSS) band. Compared with other reported single-feed wideband CP antennas, the antenna has advantages such as a wider CP bandwidth and lower backlobe radiation.

In this thesis, the circularly-polarized(CP) antenna array is designed for minimally invasive surgical positioning system. When the radar system transmits a right-handed circularly-polarized(RHCP) wave, the RHCP wave can be changed to the left-handed circular polarization(LHCP) after being reflected by the metal ,which will be suppressed cannot be received by the RHCP antenna. Therefore, the CP antenna has the advantage of the multi-path interference suppression than the linear-polarized wave, and suitable for being used in the environment containing of metal equipment, such as the surgical operation room. According to the measurement results of 22 single-layer-grounded CP antenna, the beam width with the 3-dB axial ratio is 13°, the gain is 6.7 dBi, and the polarization isolation is -14.3 dB. Another topic of the thesis is the design of three-dimensional radiation pattern measurement platform. Two step motors are used to execute the rotation of the longitudinal and elevation angles, respectively. The measurement are control softwares are realized by Arduino and LabVIEW, which handle motor control, Precision Network Analyzer (PNA) settings, data acquisition and communication. There are discrepancy between the EM simulation and measurement pattern, the cause will be discussed.
