摘　　要：典型的收发机对询问信号产生一个全向的响应,从而导致了功率的浪费;而采用传统的方向回溯天线虽然解决了收发信号定向辐射的问题,但却要求每个天线阵元都有一个相位共轭混频器电路与之对应,这对有源电路量和有限的基板安装空间都无疑增加了很大的负担.设计出了一种工作频率在X波段的四元开关馈电型方向回溯天线,并对天线设计结果进行了仿真分析,在保持传统方向回溯天线所要求辐射性能的同时,使混频器电路减少为原来的1/N,节省了发射功率,达到了优化系统的要求.Typical transponders operated with an omnidirectional response to interrogation,resulting in inefficient use of available power.Conventional retrodirective array architectures solve the problem of orientation radiation for the receiving and transmitting signal,however,this requires that each element employed a phase conjugators,which undoubtedly place a heavy burden on the amount of active circuitry requires and limits installation space of the real estate.In this paper,a switching feed network is integrated into a four-element retrodirective array architecture which operating frequency is X-band,and makes a simulation to the layout of antenna,finding out it maintained the retrodirective array＇s performance required,at the same time,mixer circuitry is reduced to 1/N,which saved transmission power and optimized system.
