摘要：

Substrate Integrated Waveguide (SIW) is a new type of guided wave structure which could be used in both microwave and millimeter wave integrated circuits. The study found that SIW's metallic via structure is very suitable for achieving fixed phase difference by different SIW widths. In this principle, a very simple way was used to realize the fixed phase shifter in equal length SIW firstly, and designed a 23GHz 3dB 180-degree H-plane directional coupler in this technique. It can achieve an over 8.7% bandwidth with +/- 0.25dB power equality, -19.2 dB isolation and 180 degrees]phase shift between the output and coupled ports.
