Abstract:In this study, a substrate‐integrated waveguide (SIW)‐based miniaturized leaky‐wave antenna (LWA) with fast beam scanning is proposed. The proposed LWA exhibits composite right/left‐handed (CRLH) property and its unit cell consist of an inverted Z‐shaped slot etched on the top layer of SIW. By sweeping frequency from 9.4 to 11.4 GHz, the proposed CRLH LWA can steer the frequency beam continuously from −40° to 51°, which shows fast beam scanning within the impedance bandwidth (2 GHz) of LWA. The good leakage co… Show more
