A compact star-shaped leaky-wave antenna for half-space steering

ABSTRACTIn this paper, a compact leaky-wave planer antenna is proposed. The proposed antenna fabricated by the printed circuit broad technology can scan a large part of its upper half-space. The proposed antenna consists of a metallic six-pointed star on a regular hexagon. The back of the hexagon is wholly covered with a conductor. The structure’s detailed design and analysis have been done using the dispersion diagram. In the proposed antenna, changing the frequency can steer the main beam in elevation at six-step angles of azimuth. The simulation and measurement results confirm the theory well. The leaky wave structure is an attractive and economical method to scan half-space.KEYWORDS: Beam scanning antennafrequency steering antennahalf-space scanningleaky-wave antennaplanar antennaDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).
