Hybrid Coupler Utilizing Substrate Integrated Waveguide (SIW) Technology for Ka-Band Applications
— This paper introduces a hybrid coupler based on SIW technology at 26 GHz and 28 GHz. High losses from the components due to the low wavelength are expected at Ka-band, primarily when planar technology is implemented. Hence, SIW structures are introduced to overcome these losses. A designed coupler based on the direct...
