Reconfigurable Leaky Wave Antenna Based On Embedded Liquid Crystal

Abstract

A liquid crystal (LC)-based leaky wave antenna (LWA) capable of wide beam steering is proposed and numerically studied. The wide-angle beam-scanning (56°) is obtained at 13.6 GHz by biasing the LC with a simple uniform bias mechanism. The unique advantages of this LWA are high realized gain, low side lobes, simple mechanism for beam steering, frequency-fixed reconfiguration, non-complex design with much reduced bias lines and control circuits, low cost, low profile, compactness, and mature of LC technology.
