5.8GHz串馈低副瓣双极化微带天线阵设计

Design of 5.8GHz dual-polarized microstrip antenna array with low-side lobe and series feed

采用串联馈电方式设计了一种工作于5.8 GHz低副瓣八元微带天线阵,该天线易于制作,具有双线极化、高增益、窄波束特性,仿真旁瓣电平为-18 dB,实测垂直极化端口S11〈-10 dB的带宽是5.5~6.5 GHz,水平极化端口S22〈-10 dB的带宽是5.7~6.6 GHz,能较好地满足ISM频段无线通信系统的要求。

Design 5.8 GHz dual-polarized microstrip antenna array with low-side lobe and series feed,it is easy to be made,high gain,Its simulated sidelobe level is-18 dB,and the measured port1 S11-10 dB is 5.5-6.5 GHz,port2 S22-10 dB is 5.7-6.6 GHz,It is suitable for ISM frequency wireless communications system.
