摘　　要：We present a Luneberg-like cylindrical lens antenna experimentally using metamaterials.The cylindrical lens antenna with a broad bandwidth is made up of the non-resonant I-shaped metamaterial structures.The near-field distributions of the metamaterial lens antenna are measured using a two-dimensional near-field microwave scanning apparatus,and agree well with the simulation results.The far-field radiation patterns of the antenna are also presented to show the high-gain performance in the broad bandwidth.We present a Luneberg-like cylindrical lens antenna experimentally using metamaterials.
