摘要
Abstract
A novel broadband dual-polarized printed dipole base-station antenna was presented. The antenna was composed of trapezoidal supported structure, integrated double inverted-L feed strips and dipoles, which was mounted on a ground plane to produce a low-profile structure. The antenna achieved a common impedance bandwidth of 1.63 ～2. 8 GHz( VSWR ＜ 1.5 ) at both input ports. It had good performance in isolation, which was more than - 28 dB between the two input ports. The cross-polarization of the antenna was better than - 20 dB and the gain is about 11 dbl. The radiation pattern and bandwidth over the operating frequency band were stable. The antenna was suitable for the GSM 1800,CDMA 1900, IMT-2000, TD-CDMA,WLAN and WiMax base station applications.关键词
