Abstract :
A full-wave optimum design of rectangular waveguide narrow-wall branch couplers is presented. The coupler is decomposed into the cascade connection of three types of building blocks whose generalized scattering matrices are obtained by mode-matching method. The overall generalized scattering matrix is obtained by cascading procedure. The optimization procedure is employed for coupler design. A WR28-band 6-dB coupler is designed, machined, and tested. Measured results agree well with computed results.
