| 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%(1.65~3.30 GHz),带宽内隔离度大于25 dB,带内增益为4.1~8.3 dBi.

| Abstract: | A broadband dual-polarized printed dipole antenna is developed for WCDMA, TD-SCDMA and some 2G/3G/4G-LET communication standard network. The antenna is composed of two double-layered printed dipoles whose polarizations are perpendicular to each other. There is a bending stair-shaped structure adopted at the bottom of strip-line balun to improve the isolation between the two port, suitable for the integration with the antenna feed network. T-shaped patchs are proposed to connect to the double-layered dipole symmetrically, to improve the bandwidth. Measurement results show that the bandwidth of the proposed antenna, achieves 66.7% for voltage standing wave ratio≤1.5(1.65-3.30 GHz). The isolation within the bandwidth is over -25 dB and the gain is within 4.1-8.3 dBi. |
