新型宽频带多频段WiFi天线的设计

内容简介：基于无线WiFi网络应用,设计一款适用于WiFi频段的宽频带多频段终端偶极天线.采用偶极天线设计原理来实现WiFi多频带,同时在天线结构正下方对天线进行耦合加载,实现驻波叠加以拓宽天线的带宽,降低天线的驻波比(VSWR),提高WiFi天线的增益(Gain)以提高天线的性能.制作加工了WiFi天线实物且实测,结果表明,基于HFSS仿真结果与实物实测的结果相当吻合,因此设计的这款天线非常适用于WiFi移动终端.

Abstract：A wideband multi?band teminal dipole antenna suitable for WiFi frequency band was designed on the basis of ap?plication of wireless WiFi network. The WiFi multi?bandand is realized with the dipole antenna design principle to achieve the increase in bandwidth of the antenna which is beneath the antenna structure,obtain active standing?wave superposition loaded by coupling,reduce antenna standing?wave ratio(VSWR),and improve the WiFi antenna(Gain)so as to improve the perfor?mance of the antenna. The WiFi antenna was manufactured and measured. The results show that the HFSS simulation results are quite consistent with physical measured results. Therefore,the antenna is ideal for WiFi mobile terminals.
