一种新型多系统共体基站天线

A Novel Multi-system Integrated Base Station Antenna

针对移动通信网络2G、3G、4G和5G多种制式并存,基站天线需兼容多个系统的要求,提出一种由肩并肩组阵和嵌套组阵组合而成的新型多系统基站天线。天线一部分由矩形低频辐射单元和1710~1830 MHz高频辐射单元嵌套组阵,天线另一部分由十字低频辐射单元和1885~2025 MHz高频辐射单元肩并肩组阵。仿真和实测结果表明,该文设计的天线工作带宽覆盖703~960 MHz、1710~1830 MHz和1885~2025 MHz,且波宽、轴向交叉极化、驻波等指标均达到预期。

In view of the coexistence of 2G,3G,4G and 5G mobile communication networks and the requirement that the base station antenna should be compatible with multiple systems,a novel multi-system base station antenna is proposed,which is composed of shoulder to shoulder array and nested array.One part of the antenna is formed by rectangular low-frequency radiation unit and 1710~1830 MHz high-frequency radiation unit in nested way,and the other part is formed by cross low-frequency radiation unit and 1885~2025 MHz high-frequency radiation unit side by side.The simulation and measurement results show that the working bandwidth of the antenna designed in this paper covers 703~960 MHz,1710~1830 MHz and 1885~2025 MHz,and the wave width,axial cross polarization,standing wave and other indicators all meet expectations.
