Abstract
A novel millimeter-wave power divider/combiner based on rectangular waveguide to multi-layer substrate integrated waveguide (RWG—MLSIW) transition is proposed in this paper. The input signal can be divided into N way directly by using multi-layer substrate integrated waveguides stacked together and plugged into a normal rectangular waveguide. A four-way multi-layer SIW power combiner operating at Ka-band is designed, fabricated and measured. Good agreement between the experiments and the simulations can be observed, demonstrating 8 GHz bandwidth (from 29 to 37 GHz) with 15-dB input return loss.
