Abstract (in Japanese) (See Japanese page) 
(in English) The circularly-polarized plate-laminated waveguide slot array antenna achieved 3.3% bandwidth for antenna efficiency more than 80% and 4.2% bandwidth for axial ratio less than 3dB in the 60-GHz band. In this paper, we propose fast analysis method for the radiating part by the method for moment. The radiating part is designed by GA. The design of the 2x2-element sub-array is improved to 14.6% bandwidth for reflection less than -14dB and axial ratio lower than 3 dB.
