A waveguide based four way millimeter-wave power combining network is studied using HFSS in this paper. The power combining network is composed of a power divider sub-network, four metal PCB cavities and a power combiner sub-network. A compact waveguide directional coupler is designed to act as the power combiner and power divider. Parameters and shapes of the PCB cavities are carefully studied to...
Magic tee is a widely used component in microwave systems; the four arms of conventional magic tee direct at four different directions, which give inconveniences to the assemblage of a system. In this paper, a narrow-wall slot directional coupler and an E-plane dielectric loaded waveguide phase shifter is used to form a magic tee with four arms in the same H-plane. The magic tee is analyzed with mode...
