This article proposes a novel circular patch antenna with polarization reconfigurability features. The antenna has a simple structure, which comprises of a radiating circular patch, embedded with two switches (PIN diode) and a pair of equal length slit on the top metal layer. By controlling the biased voltage of the PIN diodes, the polarization of the antenna can be reconfigured between three states;...
In this paper, an antenna with polarization reconfigurability is proposed. The antenna is composed of circular patch incorporated with four equal-length slits. By controlling the state of the switches, either short or open, the antenna can radiate with triple polarizations;eitherright-hand circular polarizations, left-hand circular polarizations or linear polarizations which are operated at the same...
In this paper, a circular patch antenna with polarization reconfigurability is proposed. The proposed antenna has a simple structure, consists of a radiating circular patch and two equal length perturbation slits located on the top layer of the substrate with finite ground plane on the bottom layer. In the design, two switches are used and located at the specific distance in the slits. By controlling...
