摘　　要：根据任意极化波可由空间两个正交的线极化波合成的理论,提出了一种电控变极化网络设计方案,通过功分器、3 d B电桥和可变移相器的组合形成电控变极化网络,输入的单路信号通过电控变极化网络可以形成任意极化波。仿真计算的结果表明,通过分别控制变极化网络里的两对串联移相器的相位线性变化,可以分别使合成极化波的椭圆倾角和椭圆率角产生线性变化。According to the theory that arbitrary polarized wave could be synthesized by two orthogonal linear polarized waves in space,a design scheme of electro-controlled variable polarization network was proposed.The variable polarization network was formed by the combination of the power divider、3 d B bridges and variable phase shifters.Arbitrary polarized wave can be obtained when the input signal through this kind of electro-controlled variable polarization network.The simulation results shows that the orientation angle and ellipticity angle of polarized wave can be changed linearly by controlling the phase linear change of two series phase shifters in the variable polarization network.
