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. A Concise Design of Large mm-Wave Radial Line Slot Antenna ... This paper reviews the state of the art concise design of a large aperture Radial Line Slot Antenna (RLSA) in millimeter waves to be used as a satellite on-board antenna.
