| 指出了波导结构及微带形式的TE21模圆极化合成网络的不
足，介绍了3dB分支定向耦合器的基本原理，设计了新型C频段空气带状线形式的圆极
化合成网络，并对该结构进行仿真和测试，结果满足性能要求。此种合成网络可与耦合器设
计为一体，既可以增加结构强度，还缩短了传输路径，降低了损耗，目前已经成功应用在多
种型号天线系统上。 |

| Abstract: |
| The shortcomings of waveguide and microstrip of the TE21 mode circular pol
arization synthesis networks are pointed out. The theory of equal branch wavegui
de coupler is described. A new circular polarization synthesis network is design
ed by air stripline and it is simulated and tested.This synthetic network can st
rengthen the structure,shorten the transmission path and reduce the loss by bein
g designed as a whole with coupler. This kind of combination of network has been
used in a variety of antenna systems. |
