Main-line/branch-line couplers for waveguide slot arrays
Abstract
A general four-port analysis is presented for slot couplers which link two rectangular waveguides possessing a common broadwall section. Key relations are developed which should be satisfied by any well-designed coupler intended for use in flat-plate antenna arrays. Comparison between theory and experiment is offered.
