摘要：
A novel coaxial-feed dual-polarized slot antenna with high isolation and low cross-polarization is presented. Special slots are employed for symmetrical radiation patterns at slanted +/-45 degrees polarization and low cross-polarization under -35 dB, which include two pairs of T-shaped slots and two pairs of cross-shaped slots in the radial directions of a circle patch. Moreover, high isolation of more than 36 dB between the two feeding ports is achieved by introducing two shorting pins. The experimental results demonstrate the proposed antenna is capable to operate over the frequency range of 2.23-2.91 GHz, suitable as the base station antenna for WiMAX applications.
