Aljarosha-Comm-APS2016-2017-Vol19-Jan._Feb.-007 W-band Spatial Power Combiner........

Abstract: A passive power splitter-combiner has been designed in-between two metallic ground plates using gap waveguide technology. The measured insertion loss is smaller than 2.3 dB and the return loss is larger than 10 dB over the entire W-band (75-110 GHz). The design procedure has been detailed and the simulated and measured results for the proposed structure are shown. The designed structure can be used as a passive power splitter or combiner, as a grid amplifier in a back- to-back RF chain, or as a quasi-optical beamforming component in beam steering antenna arrays.

Keywords: Gap waveguide technology, spatial power combiner, grid amplifiers.
