Abstract
A radial-line slot antenna (RLSA) is a high-efficiency planar array. A double-layered radial line and uniform slot length have been adopted in conventional RLSAs. A single-layered RLSA is much simpler in structure, but the slot length must be varied to synthesise uniform aperture illumination. The authors propose theoretical methods for the slot design. The paper presents excellent characteristics of single-layered RLSAs of small sizes (0.25–0.60 m diameter) and confirms the design. These are now commercialised for 12 GHz band DBS reception.Keywords
