Abstract

Polarization reconfigurable antenna using parasitic elements are designed for sub-6 GHz applications. A circular patch antenna is designed along with two semicircular arc - elements attached to the radiator with four diodes. By controlling the ON and OFF states of the diodes, the polarization of the antenna can be switched between LHCP and RHCP. Parasitic elements are characterized and placed around the conducting patch to enhance the gain of the antenna. The antenna exhibits a better gain of 5 dBi in both the polarization states. The prototype antenna is fabricated on a FR-4 substrate with full ground plane and tested for reflection coefficient, radiation pattern and polarization conversion ratio. The results are compared with the simulated one and they are having highest correlation between them.
