【 摘 要 】

References(14)In this letter, a broadband coupler is presented that makes use of a corrugated half mode substrate integrated waveguide (CHMSIW) technique using a printed circuit board process. The coupler is realized by parallel CHMSIW lines where the vias to form the sidewalls of the HMSIW are placed with the open-circuit quarter-wave-length microstrip stubs and the energy couples by magnetic field. Compared with conventional SIW coupler, it is easily integrated with active devices because it can isolate better the CHMSIW input/output ports from the ground plane. The coupler is simulated and measured at 9.5�?17.5 GHz. The result of measurement shows a good agreement with the result of simulation.
