Circular Polarized Antenna for Broadband Wireless System

WLAN users often complain of poor signal coverage. Most of Radio Signals suffer from Reflectivity, Absorption, penetrating obstructions, Multi-path, Inclement Weather during the propagation path and time. All of that reduce signal efficiency and wake a received signal. 1) An antenna with High gain and wide bandwidth with circular polarized suitable for the indoor and outdoor WLAN in 2.4GHz. 2) Theoretical results are obtained to satisfy good return loss requirements and specific radiation pattern shapes for the Patch antenna. 3) The practical result is still big challenge to be verified, where the project aspire to prove that down-to-earth. An antenna is a transducer that converts radio frequency electric current to electromagnetic waves that are then radiated into space. The electric field plane determines the polarization or orientation of the radio wave. In general, most antennas radiate either linear or circular polarization. Where a circular polarized antenna, the plane of polarization rotates in a circle making one complete revolution during one period of the wave.
