摘要：

A novel geometry for an antenna with polarization and reconfigurable frequency is proposed in this paper. The proposed antenna consists of an L-shaped patch antenna whose arms are separated using PIN-diode. Two parasitic elements, shorted back element, and edge tapered defected ground structure with slot are used for achieving wide impedance and axial ratio bandwidth. The proposed antenna acts as a circular polarized antenna with an axial ratio band width of 1.183 GHz and impedance bandwidth of 3.09 GHz in the ON state of both diodes and serves as a linear polarized reconfigurable frequency antenna in the remaining states of diodes.
