Abstract

In this paper, a novel eight-way Ka-band spatial power combining structure based on SIW/HMSIW is presented and studied. The power-combining structure is realized by transitions between HMSIW and parallel multiport planar microstrip lines. The power combiner is designed and fabricated in 33.5-35GHz. The measured results show a good agreement with simulation and a combining efficiency of 72% is achieved at 34.3GHz.
