Abstract
A compact,high-gain±45° dual-polarization patch antenna is proposed.A rectangular patch antenna operating in TM05 mode is investigated and modified.The out-of-phase current portions of the patch are replaced by thin microstrips,minimizing the influence of the out-of-phase currents on the radiation pattern.Considering the one-dimensional antenna array configuration required in base station applications,the thin microstrips are meandered so that the proposed antenna structure size is significantly reduced compared with that of the traditional dual-polarized antenna.A pair of differential power dividers is utilized to replace the complex feeding network of the normal antenna array,thus simplifying the structure of the antenna.The simulated S11 of the proposed dual-polarized antenna is less than-10 dB in the range of 3.4 to 3.6 GHz and the measured realized gain at the operating frequency range is greater than 11.3 dBi.关键词
