The design of a low-profile omnidirectional Circularly Polarized (CP) patch antenna is proposed. To attain the wideband impedance matching condition, this antenna uses two monopolar modes of the circular patch which is connected to a modified ground plane by means of conductive vias. The edge of the circular ground plane consists of curved branches, which are used for creating circularly polarized fields through the excitation of a degenerate mode. This antenna operates at the frequency of 2.4 GHz which is used for WLAN applications.
