Compact H-plane waveguide corners with very wide bandwidth

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.
