Beam steering left-handed leaky wave antenna for millimeter-wave applications

We propose a novel structure of left-handed leaky wave antenna (LH LWA) which can steer the radiation angle for a fixed frequency. A unit cell has been designed at 78 GHz by full-wave simulated dispersion characteristics, and a backward-to-forward beam scanning antenna has been numerically demonstrated. The beam scanning angle is +18/spl deg/ to -23/spl deg/ at 78 GHz.
