Abstract

A dual-polarized shorted bowtie antenna integrated with a cross dipole is presented. The electric cross dipole is added to generate a symmetric radiation pattern and to compensate the high back radiation due to the shorted patches. This novel dual-polarized antenna is designed for the existing DCS, PCS, and 3G mobile communication systems working between 1.71 and 2.17 GHz. Stable and symmetric radiation patterns at slanted plusmn45deg polarization have been obtained over the operating frequency bands. Measured isolation between the two input ports is over 28 dB. The gain of the proposed antenna is also stable with frequency. The average is about 6.6 dBi
