Abstract

In this paper, we proposed the dual polarization antenna for DCS, UMTS, and WiBro bands. To extend the impedance band width, the proposed antenna used the square loop radiators. In addition, by square loop radiators, the dimensions of an antenna are reduced. As a result of measurement after compensation, we can see that the first port is less than -14dB, the second port is less than -14dB and intra isolation is less than -25 dB. Additionally, a gain of the antenna is more than 9dBi. This polarization diversity antenna element can be used to form an array antenna for a wireless communication base station.
