Abstract (in Japanese) (See Japanese page) 
(in English) We design a post-wall waveguide slot subarray for 76.5 GHz band with a structure of 25 radiating elements that can suppress E-plane sidelobe. First, by adjusting the shape of the feeding aperture, the feeding part is designed to suppress reflection. Then, the slot length and post position are adjusted, and the radiating elements are designed so that the excitation distribution calculated from the Taylor distribution is obtained. The overall structure is analyzed by combining the radiating section, in which the radiating elements are arranged so that their excitation phase distribution is uniform, and the feeding part. The reflection is less than -10 dB in a range of 74.1 GHz to 76.4 GHz, and the sidelobes are sufficiently suppressed at the design frequency.
