摘要：

This paper proposed a SIGW wideband 3-dB coupler that operates mainly in the Ka-band by combining the SIGW theory and the theory of branch-line coupler. Firstly, the structure of the SIGW is analyzed. Then, the coupler is designed using the SIGW transmission line with five-branch to realize a wideband. Finally, the proposed SIGW coupler is fabricated and measured, and the measurement results are consistent with the simulation results. The SIGW coupler centered at 30 GHz has a 40% wide bandwidth (24-36 GHz). The return loss of the coupler is better than 10 dB and the isolation is better than 17 dB. The SIGW coupler in this paper has a wide operating bandwidth, high isolation, and is easy to fabricate compared to conventional branch-line couplers.
