摘　　要：提出了一种小型宽频带的六边形缝隙天线。通过在接地面的中心位置刻蚀出六边形缝隙并加载和缝隙形状相似的的寄生贴片实现了天线的宽频带。用仿真软件HFSS对天线进行仿真分析,并对天线进行了实际测试。结果表明,所提出的天线的带宽达到了9GHz(3.50~12.50GHz),阻抗相对带宽达到了113%,频带内电压驻波比小于2,阻抗匹配良好,同时,在整个频带内,增益均大于3.5dB,最大增益达到4.5dB,测试结果和仿真结果基本上一致。该天线可应用于宽频带无线通信系统。A compact wide-band hexagon slot antenna was proposed.Wideband of the antenna was achieved by etching hexagon slot and loading parasitic patch at the center of the ground plane.The antenna was analyzed using simulation software HFSS and then measured practically.The results show that the bandwidth of the proposed antenna could reach 9GHz(3.50 GHz to12.50GHz),and impedance relative bandwidth could achieve 113%.In the whole band,the VSWR is less than 2,and impedance matching is pretty good.At the same time,in the whole frequency band,gain is greater than 3.5dB,and the maximum gain could attain 4.5dB。Measured and simulated results are basically consistent.The antenna can be used in broadband wireless communication system.
