AbstractIn this paper, we propose an improved shunt-capacitance-aided composite right/left-handed (CRLH) leaky wave antenna (LWA) with large beam-scanning-range (BSR)/bandwidth ratio based on substrate integrated waveguide (SIW) structure. The CRLH LWA is constructed by etching interdigital capacitor on the waveguide surface, which behaves as the series capacitor for left-handedness as well as radiating cell. Two longitudinal slots locate at upside and downside of the interdigital capacitor, respectively, which are working as the aided shunt capacitance to achieve large BSR/bandwidth ratio. An X-band LWA composed of 15 CRLH cells is fabricated. The simulated results of S-parameters and radiation patterns are presented. Compared with other frequency scanning CRLH LWAs reported before, this LWA has the advantage of large BSR from -57 degrees to +65 degrees within a fractional bandwidth of 28% (from 9.2 GHz to 12.2 GHz).
