[Abstract]:As an important part of modern wireless communication system, antenna and electronic science and technology are developing rapidly in the direction of miniaturization, high performance and high integration. Substrate integrated waveguide back-cavity slot antenna is a new type of antenna. It has the characteristics of small size, light weight, low loss, high Q value and low cost. In addition to the manufacturing features which are easy to integrate with the existing planar microwave circuits, it also has the inherent characteristics of high performance, high power capacity, high thermal stability and structural stability, which are inherited from the traditional metal waveguide slot antennas. Therefore, the basic application research of miniaturized substrate integrated waveguide back-cavity slot antenna is not only of important theoretical value but also of engineering practical significance for the realization of high performance and high integration of modern microwave millimeter-wave passive devices and active circuits. In this thesis, rectangular, hexagonal substrate integrated waveguide and rectangular half-mode integrated waveguide back cavity slot antenna are taken as the research objects, and its miniaturization technology is studied. The gain enhancement is achieved by integrating the higher-order TE or high-order quasi-TM resonant modes in the waveguide resonator with the multi-slot structure. The technique of expanding the impedance matching bandwidth between the waveguide resonator and the 110HTE and 210HTE hybrid resonant modes in the resonator by rectangular half-mode substrate is also presented. Firstly, the basic theory and technology of the design of the slot antenna in the substrate integrated waveguide are introduced. Based on the brief introduction of the main characteristic parameters of the antenna, the basic principle and design method of the traditional resonant metal waveguide slot antenna are analyzed in the form of mathematical derivation. The basic theory of substrate integrated waveguide technology and the resonant characteristics of various types of cavity are briefly reviewed, which lays a theoretical and technical foundation for the design of a miniaturized substrate integrated waveguide back cavity slot antenna. Secondly, two small rectangular substrate integrated waveguide slot antennas with high order TE resonant mode are designed and implemented. Through these two antennas, the radiation principle of the substrate integrated waveguide back cavity slot antenna is analyzed preliminarily, and the antenna is miniaturized by coplanar waveguide structure. The gain of the antenna is improved by the high order TE resonant mode and multi-slot structure in the rectangular substrate integrated waveguide. Then three miniaturized hexagonal substrates integrated waveguide slot antennas with quasi-TM resonant mode are designed and implemented. The antenna is miniaturized by bending and deforming slot structure. The metallized through hole array which acts as a perturbation helps to excite the higher-order resonant mode and suppress the interference resonant mode. The gain of the antenna is improved by the high-order quasi-TM resonant mode and the multi-slot structure in the hexagonal substrate integrated waveguide. Finally, two miniaturized rectangular half-mode integrated waveguide back-cavity slot antennas using the hybrid resonant mode of 110HTE and 210HTE are realized, and the antenna is miniaturized through the half-mode integrated waveguide resonator structure. The impedance matching bandwidth of the antenna is extended by the rectangular half-mode substrate integrated waveguide cavity with the mixed resonant modes of 110HTE and 210HTE in the cavity.
