【摘要】：设计一种可用于W-CDMA,TD-SCDMA等2G/3G/4G-LTE通信标准网络的宽频带双极化印刷振子基站天线单元.天线由两个双层贴片结构十字交叉组成,在馈电巴伦底部采取梯形弯曲结构,提高了双端口的隔离度,便于组装;在贴片双臂上端附加短路T形贴片结构,展宽了带宽.实测结果表明:天线两端口电压驻波比≤1.5的带宽均达到66.7%(1.65~3.30GHz),带宽内隔离度大于25dB,带内增益为4.1~8.3dBi.
[Abstract]:A broadband dual-polarization printed dipole base station antenna unit is designed for W-CDMA-TD-SCDMA and other 2G/3G/4G-LTE communication standard networks. The antenna is composed of two double layer patch structure cross, adopts trapezoidal bending structure at the bottom of feed Barron, improves the isolation degree of double ports, and adds short circuit T-shaped patch structure to the upper end of the patch arms, which broadens the bandwidth. The measured results show that the bandwidth of the antenna with VSWR 鈮，
