Abstract

A wideband dual-polarized antenna for LTE (Long Term Evolution) communication system is presented. The antenna is excited by inverted L-shaped strip feed line. A wide impedance bandwidth operating from the frequency 1.71GHz to 2.69 GHz with Voltage Standing Wave Ratio(VSWR) less than 1.5 is achieved. The isolation of the antenna between the two input ports is over 40dB. Stable radiation patterns with low cross-polarized, low backlobe radiation and gain of 9dBi have been obtained across the entire operating frequency bands.
