| 摘 要： | 采用多层贴片、垂直双H型孔径耦合结构设计了一种高隔离度双极化孔径耦合微带天线。主要通过实测分析不同贴片间距以及孔径大小对天线隔离度的影响，确定了最佳贴片间距和孔径尺寸。经AgilentES062A矢量网络分析仪实测，得出天线两个端口的回波损耗在2．4～2．5GHz能达到一16dB以下，在工作频段内双端口隔离度优于一31dB，与仿真结果吻合较好。该设计结构简单，成本低廉，易于制作，且可作为双极化基站阵列天线单元。

| Abstract: | A dual-polarized aperture coupling micro-strip antenna with high isolation is introduced which using a structure of multi-layer patches and vertical dual-H shape aperture coupling. The influence of different distances between patches and different aperture sizes in the antenna isolation is analyzed through the test, and the best patches distance and aperture size is determined. The test result of VNA Agilent ES062A shows that the return loss in both ports is lower than -16 dB when the frequency is between 2.4 GHz and 2.5 GHz, and the isolation of dual ports is better than -31 dB in the work frequency range. The test result coincides well with the simulation results. The design is simple, low cost, easy to be made, and can be used as the unit of dual-polarized base station array antennas. |
