Abstract
A steerable Ka-Band leaky wave antenna (LWA) based on liquid crystal is presented. Beam steering is achieved by tuning a dielectric layer of liquid crystal by means of a static magnetic field which is confirmed by the measured dispersion characteristics and far field patterns. The LWA shows a beam steering range larger than 8 degrees for the frequencies between 26 GHz and 28 GHz.
