In this paper,a novel four-way radial waveguide power divider with low insertion loss and high power-handling capacity is proposed.This power divider consists of an input coaxial waveguide,a central probe,a radial waveguide,four equispaced identical coupling probes,four equispaced identical adjusting posts and four output coaxial waveguides.The novel coupling probes and the adjusting posts are used to realize favorable uniform power division.A power divider with the center frequency of 4.1 GHz is designed,fabricated and measured.Good agreement between simulation and experiment is noted.The measured 15 dB return-loss bandwidth of the power divider is about 600 MHz.The measured 0.5 dB insertion loss bandwidth is wider than 700 MHz.The differences and isolations between the output ports are also discussed.The power-handling capacity of the power divider is analyzed through simulation,and the result proves its usability in high power applications.
