摘　　要：针对同轴布喇格结构的特点,设计一种Ka波段正弦开槽同轴布喇格放射器。介绍多模耦合理论与CST商业软件,在此基础上对其进行参数设计和数值模拟研究。结果表明:多模耦合理论与CST商业软件两者吻合较好;根据实际需要,可通过改变初始相位、开槽深度、加坡度方式和坡度角以及加窗技术等来提高Ka波段同轴布喇格反射器频率响应的性能;有利于改善同轴布喇格结构作为反射器或者滤波器的性能。Aiming at the characteristic of coaxial Bragg structure,design a coaxial Bragg reflector corrugated with sinusoidal ripples operating at Ka-band.Introduce the coupled mode theory and the CST software,based on of this,research its parameter design and numerical simulation.Results show that good agreement between the multi-mode theory and the CST software;In fact,by changing the initial phase,sinusoidal ripple amplitude,shape of gradient and gradient angle and windowing-function technique can improve the capability of the frequency response.These characteristics of a coaxial Bragg structure are favorable to improvement of the performance as a reflector or a filter in its applications.
