Abstract

In this paper, modified triangular-shaped waveguide-typed septum polarizer has been suggested and verified by using commercially available software and carrying out the comparison with the conventional rectangular waveguide-typed polarizer. It is expected that the proposed structure shows the better electrical performances than the conventional one in terms of the smooth energy-transfer of TE10 and TE01-modes. The simulated result shows that the proposed structure accomplished axial ratio of less than 0.32dB, return losses of lower than −32dB, and isolation characteristics between −24dB and −35dB at the target frequency ranging from 8 to 8.4GHz.
用于卫星通信的三角形阶梯隔膜偏振器
本文提出了一种改进的三角形波导型隔膜偏振器,并利用市售软件进行了验证,并与传统的矩形波导偏振器进行了比较。期望该结构在TE10和te01模式的平滑能量传递方面表现出比传统结构更好的电学性能。仿真结果表明,在8 ~ 8.4GHz目标频率范围内,该结构的轴比小于0.32dB,回波损耗小于- 32dB,隔离特性在- 24dB ~ - 35dB之间。
