A novel wideband four-way divider/combiner based on substrate integrated waveguide (SIW) and double-layer finline is presented. This divider/combiner designed at 29-40 GHz is mainly composed of the double-layer finline transition from waveguide to SIW and the double-microstrip transition from SIW to microstrip. These transitions feature the function of power divider/combiner, as well as the function of transition. The measured power-combining efficiency of this circuit at 35.6 GHz is 86%, and the combining efficiency is higher than 75% at 29-40 GHz.
