Antennas are a very important com-ponent of communication systems. A micro strip or patch antenna is a low-profile antenna that has a number of advantages over other antennas. Circularly polarized (Cp) antennas are widely used in modern wireless systems because they can suppress multipath interferences and relax the alignment requirement for the transmitting and receiving antennas. For mobile communi-cations, omnidirectional conical radiation patte-rns are generally desirable for they can provide larger coverage. They have immunity to multi-path distortion and polarization mismatch losses. On the other hand, omnidirectional radiation patterns are generally desirable since they can provide larger signal coverage and stabilize the signal transmission. Most modern wlans are based on IEEE 802.11(2.4ghz) standards and are marketed under the Wi-Fi brand name. Several Wideband and Low-Profile Omnidirectional Circularly Polarized Patch Antenna designed a circularly polarized (CP) patch antenna is studied.
