摘要
针对多通道固态源腔内定向加热系统成本过高的缺陷,本文提出了通过馈电网络使用单通道固态源实现腔内三分区加热的方法,并基于威尔金森功分器和传输线理论,设计了一种通过输入频率变化调节输出相位的微带功分馈电网络。仿真结果表明工作频带内端口输出幅度一致,相位值可满足腔内定向加热相控阵天线的需求,使用COMSOL构建模型,验证了通过馈电网络实现一源三分区加热系统的可行性。
In view of the high cost of multi-channel solid-state generator intracavity directional heating system,a method of intracavity three zone heating using single channel solid-state generator through feed network is proposed.Based on Wilkinson power divider and transmission line theory,a microstrip power division feed network with output phase modulated by input frequency variation is designed.The simulation results show that the output amplitude of the port is consistent in the working frequency band,and the phase value can meet the requirements of intracavity directional heating phased array antenna.A COMSOL model is used to verify the feasibility of realizing one generator three zone heating system through feed network.
