Abstract

Commonly, the classical formulas for designing TE₂₁-mode coupler are suitable for the operating frequency under Ka-band by virtue of ignoring wall thickness. However, in real application of TE₂₁-mode coupler design beyond Ka-band, the new formulas need to consider the effect of wall thickness. Herein, we demonstrate a design measure of a TE₂₁-mode coupler beyond Ka-band via computer simulation, giving attention to wall thickness. The experimental results show that a measure of linear second weighted sum for coupling hole size could improve coupler performance. Amazingly, such coupler shows 10% bandwidth with less than 0.5 dB coupling loss and more than 40 dB isolation is possible.

壁厚对ka波段te21模耦合器宽带设计的影响

通常，经典的te21模耦合器设计公式由于忽略壁厚，只适用于ka波段下的工作频率。然而，在实际应用的ka波段以外的te21模耦合器设计中，新公式需要考虑壁厚的影响。在此，我们通过计算机模拟展示了一个超越ka波段的te21模式耦合器的设计测量，并考虑了壁厚。实验结果表明，对耦合孔尺寸采用线性二次加权和的方法可以提高耦合性能。令人惊讶的是，这种耦合器显示10%的带宽，耦合损耗小于0.5 dB，隔离度超过40 dB。
