本文研究了脊波导中心对称加载铁氧体环移相器的差相移、插入损耗和LSE_(20)模的截止波长,理论差相移与实验结果基本一致。此外,还给出了适用于脊波导、背脊波导和矩形波导三种结构移相器的相位常数和LSE_(20)模的截止波长的超越方程,以及插入损耗表达式。计算了三种不同波导移相器的相对插入损耗与频率的关系曲线。
In this paper, we study the differential phase shift, insertion loss and the cutoff wavelength of LSE_ (20) modes of a symmetrically loaded ferrite ring shifter in a ridge waveguide center. The theoretical phase shift is consistent with the experimental results. In addition, the transcendental equations of the phase constant and the cut-off wavelength of the LSE_ (20) modes, as well as the expressions for the insertion loss, are presented for the three structure phase shifters of the ridge waveguide, the ridge waveguide and the rectangular waveguide. The relative insertion loss versus frequency for three different waveguide phase shifters was calculated.
