A dual-band beam-sweeping antenna based on two independent cylindrical active frequency selective surfaces (AFSSs) is proposed in this paper. This antenna is composed of a dual-band omnidirectional monopole antenna operating at 2.45 and 5.2 GHz and two cylindrical AFSS screens. The dual-band omnidirectional monopole antenna is designed as a radiating source and surrounded by the proposed two cylindrical...
A dual-band reconfigurable radiation pattern antenna based on active frequency selective surfaces (AFSS) is presented. This antenna is composed of a dual-band omni-directional patch antenna and two cylindrical AFSS with the operating frequencies of 2.45 GHz and 5.2 GHz, respectively. The unit-cells of the proposed AFSS consist of the two metallic crosses connected by a pin-diode vertically. The transmission...
In this paper, a beam switching antenna with a novel active frequency selective surface (AFSS) is proposed at 5.2 GHz. The antenna is composed of an omnidirectional patch antenna and AFSS. The AFSS is made up of 6 columns, each with 2 unit cells, which are placed vertically around a patch antenna to form a hexagonal wall. To steer beam of the antenna, high frequency pin diodes are precisely inserted...
