Abstract :
The design of crossed-SIW 3-dB directional couplers with different angles has been presented in this paper. A prototype coupler was fabricated by PCB process. Measured results prove the design´s validity and show fine agreement with the simulation ones. Further work could be done to enlarge the operating bandwidth by design a better H-plane transition structure from central cross region to extended SIW sections.
