摘  要: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 1 710 ~ 1 830 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 1 885 ~ 2 025 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、1 710 ~ 1 830 MHz 和 1 885 ~ 2 025 MHz,且波宽、轴向交叉极化、驻波等指标均达到预期。

Abstract: 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 1 710 ~ 1 830 MHz high-frequency radiation unit in nested way, and the other part is formed by cross low-frequency radiation unit and 1 885 ~ 2 025 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, 1 710 ~ 1 830 MHz and 1 885 ~ 2 025 MHz, and the wave width, axial cross polarization, standing wave and other indicators all meet expectations.

Keywords: base station antenna; multi-frequency; nesting; mobile communication
