Circularly Polarized (CP) antennas are widely used in modern wireless communication systems because of their immunity to multipath distortion and polarization mismatch losses. On the other hand, unidirectional radiation patterns are generally desirable since they can provide larger signal coverage and stabilize the signal transmission. As a result various Omni directional CP antennas have been proposed and investigated over the past few years. The design utilizes two monopole modes of a circular patch which connects to a modified ground plane by a set of conductive pins, to achieve wide-band impedance matching.
