摘　　要：基于特征模理论设计了一种WiFi 6E的小型化天线,主要由L型和Y型金属构成。基板尺寸为12 mm×12 mm×1.6 mm,介质基板底部由L型地板构成,上表面布置3个L型金属和1个Y型金属。为了改善阻抗匹配效果、增加天线的带宽,将2个小型的L型金属排布在Y型主干的两侧,另外一个放置在Y型金属的对面。仿真结果表明:该天线可覆盖4.92~8.14 GHz,中心频点处的回波损耗小于-32 dB,在WiFi 6E的频带内有较好的定向辐射特性,且覆盖频带宽,具有良好的应用前景。A miniaturized WiFi 6E antenna is designed based on characteristic mode theory,which is mainly composed of L-shaped and Y-shaped metals.With substrate size 12 mm×12 mm×1.6 mm,the bottom of the dielectric substrate is composed of L-shaped floor,three L-shaped metals and one Y-shaped metal arranged on the upper surface.In order to improve the impedance matching effect and increase the bandwidth of the antenna,two small L-shaped metals are arranged on both sides of the Y-shaped backbone,and the other is placed opposite to the Y-shaped metal.Simulation results show that the antenna can cover 4.92-8.14 GHz,and the return loss at the centre frequency is less than-32 dB.It has good directional radiation characteristics in the frequency band of WiFi 6E,and the cover has wide frequency band,so it has good application scenarios.
