Abstract
An antenna is located at the end of a wireless communication system, or other radio system, and more particularly, a wideband planar antenna with linear and circular polarization uses different polarization for transmission or reception to increase the isolation between the transmission and reception by suggestion and using a type of radiation element. The disclosed antenna is more efficient than other similar antennas that can transmit/receive linear or circular polarization. The disclosed invention makes it possible to pr vide an antenna having dual polarization, which has an orthogonal characteristic in both linear and circular polarization, and which can lower the height of the antenna by embodying a micro strip planar antenna which has linear and circular polarization that has high gain over a wide frequency band, and which transmits/receives linear or circular polarization.
