A low-cost and high-gain dual-polarized wideband millimeter-wave antenna

This paper introduces a novel dual-fed dual-polarized antenna for millimeter-wave applications. Both a very large impedance bandwidth (11.33 GHz) and a high gain (peak value of 12.9 dB) are achieved with a simple low-cost hybrid configuration. The isolation between the two independent feed ports is better than 19 dB across most of the operating bandwidth.
