介绍了一种矩形波导宽边四元中心斜缝天线的设计,简要阐述了宽边斜缝阵列天线的理论依据和设计原则。利用算得的参数,借助CST软件的参数扫描功能,通过局部地调整设计参数就可以方便地得到天线的谐振参数,并对天线进行了仿真分析。仿真结果表明,该天线在切割四个缝的情况下即能够实现设计指标的要求,且天线性能良好。
This paper introduces the design of a wide rectangular quadrangle waveguide antenna with rectangular waveguide. The theoretical basis and design principle of the broadside slant array antenna are briefly described. By using the calculated parameters and using the parameter scanning function of the CST software, the resonance parameters of the antenna can be conveniently obtained by locally adjusting the design parameters, and the antenna is simulated and analyzed. The simulation results show that the antenna can meet the requirements of design index when cutting four slits, and the antenna performance is good.
