提出了一种具有四个端到端折叠振子和一个U形接地的宽带双极化天线。在1.71-2.17 GHz频段内，获得了倾斜±45°极化下稳定对称的辐射方向图。测量结果表明，两个线性极化的隔离度超过30分贝的工作频带。回波损耗小于−14 dB，测得的交叉极化电平比上述频段内的同极电平低23.5 dB。
A broadband dual-polarised antenna with four end-to-end folded dipoles and a U-shaped ground is presented. Stable and symmetric radiation patterns at slanted ±45° polarisation have been obtained within the band 1.71–2.17 GHz. Measurements show two linear polarisations with an isolation of more than 30 dB over the operating frequency band. A return loss less than −14 dB is achieved and the measured cross-polar level is 23.5 dB below the co-polar level within the above-mentioned band.
