چكيده فارسي :
In this paper, a Bethe hole coupler is designed and presented using groove gap waveguide (GGW) technology for operation at Ku Band covering 12–17GHz frequency range. Simulation results show the operating bandwidth of more than 40% and the isolation of more than 25dB for the designed coupler. GGW technology gifts the proposed structure the advantage of easy fabrication especially at high frequencies thanks to no electrical connection requirement between the metal block of the structure. Also, due to the propagation of the wave in the air, lower losses is introduced compared to SIW and microstrip like counterparts.
