Holographic Antenna Based on Artificial Modulated Impedance Surface

In this paper, a two-dimension holographic antenna based on artificial modulated impedance surface operating at 5GHz is proposed. By changing the feeding phase difference between the adjacent one-dimension leaky-wave antennas, continuous beam scanning at two-dimension space can be realized. When the feeding phase difference changes from -90° to 90°, the radiation direction in H-plane changes from -27° to 27°, which makes our design a great practical application in reconfigurable antenna.
