Abstract
This paper presents the design and results of a planar lens fed by a fan beam H-plane horn antenna. Compared with traditional dielectric lens antenna, planar lens based on metamaterials is composed of several unit cells designed for changing the phase of incident wave. The presented lens is center-fed by a horn antenna located at 100mm from the lens, and the thickness of it is 5mm. The simulation results exhibits a high gain of 30dB at 76.5GHz and a fan-shaped main beam with half-power beamwidths of 1.7° and 4.1° on E-plane and H-plane respectively.
