本文描述了紧凑的H平面直角转角，它带有一对匹配的金属柱，其轴线平行于TE10模的电场。有些拐角是通过在方形弯头区域适当地布置柱子而成功地设计的。具有一个或两个柱子的角落可以在特定带宽上以任意中心频率匹配。此外，优化的三金属柱转角的带宽覆盖了整个X波段或更多频段，回波损耗优于40d B。由于H平面中的平面结构，上述角点采用H平面平面电路方法设计。通过有限元仿真(HFSS)验证了设计思想和设计步骤的正确性，并对宽带三柱转角进行了实验验证。
This paper describes compact H-plane right-angled corners with a couple of matching metallic posts with axis parallel to the electric field of a TE10 mode. Some corners are successfully designed by properly arranging the posts in their square elbow region. Corners with one or two posts can be matched at an arbitrary center frequency over a certain bandwidth. Furthermore, it is shown that the bandwidth of an optimized corner with three metallic posts covers a full X-band or more with very low return loss better than 40 dB. The above corners are designed using the H-plane planar circuit approach because of the planar structure in the H-plane. The validities of the design concept and procedures are confirmed by em-simulations (HFSS), and the wideband corner with three posts is verified experimentally also.
