提出了一种适用于工业、科学、医学(ISM)频段的六边形缝隙天线的设计方法，采用基于全波分析矩量法的电磁场仿真软件进行分析，结果表明，与传统的正方形缝隙天线相比，天线的阻抗带宽由30%增加到了48.5%(|S₁₁|<-10 dB)。进行了天线S 参数测量，对天线通带起始频率5.24 GHz、谐振频率5.8 GHz和截止频率8.59 GHz三处频点的方向图进行了测量，测量结果和仿真结果一致，为拓展微带贴片天线带宽提供了一种新颖的方法。

A novel hexagon slot antenna which operates at Industrial, Scientific, and Medical(ISM) band is proposed. The simulation results of method of moments based on full wave analysis indicate that the bandwidth of the proposed antenna increases from 30% to 48.5%(|S₁₁|<-10 dB)compared with a traditional square slot antenna. The |S₁₁| of the fabricated antenna is measured. The radiation patterns at 5.24 GHz, 5.8 GHz and 8.59 GHz, which are the initial frequency, resonance frequency and cut-off frequency of the passband, respectively, are measured in a microwave chamber as well. The measured results agree well with the simulation results. This work provided a novel method to broaden the bandwidth of microstrip slot antenna.
