Reconfigurable antenna with high-directive beam using active cylindrical PRS

In this paper, the design method for an antenna with the high level of the directivity in the E-plane and the capability of turning radiation pattern has been proposed. The array of dipoles is used as radiating source. The antenna has advantage of using active PRS for controlling the direction of radiation pattern instead of using phase shifters. The active PRS also increase the directivity of antenna about 7 dB. With these features, the proposed antenna is suitable for applications in the base station of wireless communication systems.
