Design and Performance Analysis of High Power Microwave Antenna Based on Microwave Photonic Materials
With the continuous development of technology, the demand for high power microwave antenna is increasing. This type of microwave antenna is required to have the characteristics of compact structure, low error rate and strong environmental adaptability. Therefore, the design of microwave antennas with superior performance has become a hot topic of research by many scholars. In this paper, a high power microwave antenna based on microwave photonic materials is designed. The theory of microwave electronic materials is further studied and the physical parameters of the surface structure of microwave electronic materials are analyzed by the equivalent dielectric model LC resonant circuit. At the same time, the design index of the traditional microwave antenna is discussed. Using the transmission line theory and the slight interference method, the propagation constant function curve and the attenuation constant function curve of the microwave antenna are obtained, the numerical simulation is carried out, and the reasonable design parameters are determined. In the design process, the microwave photonic material is taken as the outer layer and loaded into the design of the microwave antenna, and the microwave photonic material+the microwave antenna is obtained. Compared with the microwave antenna without loading microwave photonic material, the optimum resonant frequency of the microwave photonic material loaded microwave antenna is 11.78 GHz. The microwave antenna with microwave photonic material can obtain higher signal gain, and the radiation range is obviously lower than that without loading microwave photonic material.
