Abstract :
In recent years, various types of system in millimeter-wave band have been developed. In a millimeter-wave system, it is suitable to make use of an antenna without feed loss. A radial line slot antenna (RLSA) is a slotted waveguide planar antenna proposed for direct broadcast from satellite (DBS) subscribers in the 12 GHz band. Since this antenna utilizes a waveguide as a feed circuit, a high efficiency is theoretically expected irrespective of the frequency. This paper presents the design of RLSA at 60 GHz band and predicts its performance.
