摘要
天线辐射信号时,自身会存在一定大小的驻波,而相控阵天线的单元间还存在互耦效应,使得天线的驻波增大,会对发射机功放组件造成一定的损坏,因此,在设计相控阵天线时,必须考虑驻波的大小及其影响。针对此问题提出了一种测试相控阵天线驻波大小的方法,将驻波分为自耦部分和互耦部分,分别进行测试,并相加得到总的驻波,并与仿真结果进行了对比验证,证明了测试方法的有效性。
Antenna has standing wave when radiating signals,and there is mutual coupling between units of phased-array antenna,which increases the standing wave and does great harm to the power amplifiers of the transmitter.Therefore,the effects of standing wave need to be taken into consideration when designing a phased-array antenna.Based on the problem,a test method of standing wave in phased-array antenna is put forward.Standing wave can be divided into self coupling and mutual coupling,testing each of them and the total standing wave is obtained by adding.The results are compared with the simulation results,which proves the validity of the test method.
