Abstract

A broadband dual polarized patch antenna for base stations is proposed. The proposed antenna consists of two-layer patches fed by four capacitive F-probes. A balanced feeding with 180 ^° phase shifts is used to realize the high isolation and low cross polarization. Surrounding copper frame is added to reduce the back radiation. A prototype of the proposed antenna is fabricated. It has a measured 45% relative bandwidth (1.71-2.72 GHz) for , which covers the DCS/PCS/UMTS/LTE2300/LTE2500 bands. The measured isolation between the two ports is about 30 dB and XPD is above 23 dB at broadside. The proposed antenna is suitable for applications in mobile communication base stations.
