| Abstract: | A single-layered radial line slot array (SL-RLSA) antenna etched on a substrate and fed by a rectangular waveguide is presented in the 60 GHz band. The design curves are obtained by an efficient electromagnetic coupling analysis using Ewald sum technique and Shanks' transformation. The antenna has rectangular waveguide feed structure using a rectangular waveguide-to-radial line transition. The prototype antenna of 10 cm diameter was tested and the gain of 30 dBi was measured at 60 GHz |
