高功率天馈系统的设计——可控相位波导阵列天线

Design of High Power Antenna Feed System-phase-regulated Waveguide Array Antenna

以磁化等离子体为终端负载，设计一种可控相位波导阵列天线的天馈系统，通过相邻波导间相位的任意调节，可以获得所期望的Ｎ１１功率谱，从而把高功率的微波有效地耦合到等离子体中。数值计算表明，该系统完全满足所设计的要求，为系统的设计提供了理论依据。

A phase-regulated waveguide array antenna that takes magnetic plasma as terminal load is designed in this paper. Expecting N 11 power spectrum is obtained by adjusting phase between waveguides, therefore high power microwave is effectively coupled into plasma, Simulation results agreed well with analytical results and provided theoretical bases.
