A full band millimeter wave power module using microstrip to waveguide 3dB power splitter/combiner
In this paper, to realize broadband power combine, we presents a full band microstrip taper probe splitter/combiner(MTPS/C), which is in the context of WR-28 waveguide and 50 Omega-microstrip line supported by duroid 5880 (epsivr=2.2, h=0.254mm). The proposed 3dB splitter shows excellent performance across the entire waveguide band. And finally a full band power module is design based upon the splitter/combiner proposed and show excellent performances across the entire band of WR-28.
