我们提出了一个h形旋转关节，使用隔膜偏振器。利用三维电磁场分析软件设计了一种新型偏振器。我们测量了串联在一起的两个偏振器的性能。我们发现，在35-41 GHz频率范围内，插入损耗小于0.8 dB，回波损耗小于- 15 dB，隔离度小于- 17 dB，相应的分数带宽为~15%。这些结果证明了h型旋转接头的有效性。
We propose an H-shaped rotary joint that uses septum polarizers. We designed a new polarizer using three-dimensional electromagnetic-field analysis software. We measured the performance of two polarizers connected in series. We found that the insertion loss was less than 0.8 dB, the return loss was less than −15 dB, and the isolation was less than −17 dB in the frequency range 35–41 GHz, corresponding to a fractional bandwidth of ~15%. These results demonstrate the effectiveness of the H-shaped rotary joint.
