Abstract :
The tilted installation of the feed waveguide is proposed to reduce the overall reflection at the input aperture in a post-wall waveguide-fed parallel plate slot array. Two types of tilting are proposed. The suppression of the overall reflection around the design frequency is confirmed by the approximated estimation and the experiments.
