Abstract :
In this letter, a simple low-loss planar spatial power-combining architecture based on half model substrate integrated waveguide (HMSIW) is proposed and studied. The power-combining structure is realized by transition between a HMSIW and parallel multiport planar microstrip lines. The power combiner is simulated and measured at 34.5-36.5 GHz. Measured results show a good agreement with simulation and a combining efficiency of 82% is achieved at 35 GHz.
