摘要
为了适应新一代通信技术对天线性能提出的更高要求,提出了一种宽带高增益超表面天线。该天线通过在缝隙天线上方加载超表面,不仅展宽了天线的带宽,还进一步提高了天线的峰值增益。仿真结果表明,该天线的-10-dB阻抗带宽为930 MHz(4.77-5.7 GHz),相对带宽为17.8%,在工作频率5.2 GHz处的峰值增益为8.05 dBi,同时实现了宽带、高增益和定向辐射的性能。
In order to meet the higher requirements of the new generation communication technology for antenna performance,a broadband high gain metasurface antenna is proposed in this paper.By loading a metasurface above the slot antenna,the bandwidth of the antenna is broadened;also the peak gain of the antenna is further improved.The simulation results show that the-10-dB impedance bandwidth of the antenna is 930 MHz(4.77~5.7 GHz),the relative bandwidth is 17.8%,and the peak gain is 8.05 dBi at 5.2 GHz.The antenna achieves the performances of broadband,high gain and directional radiation simultaneously.
