摘要
工作频率为3．4～3．6GHz的低旁瓣十六元微带缝隙天线阵的设计方法，应用微带缝隙天线的理论及馈电方式设计天线阵元。通过谢昆诺夫单位圆辅助分析法对天线阵进行优化设计后，可实现天线增益为17．6dBi，而上侧第一副瓣电平能够达到-18dB，与同类产品相比是比较先进的。天线在Wimax宽带无线局域网接入中应用，具有良好的性能。借助Ansoft HFSS仿真软件对天线进行了仿真，仿真结果和实验结果基本一致。
The design of low-lobe 16 microstrip slot antenna array where the working frequency is 3.4-3.6 GHz is introduced in this paper. The antenna array elements were designed by applying micro-strip slot antenna theory and feed way. Schelkunoff units assisted analysis method was used to optimize the design and an antenna gain of 17.6 dBi can thus be realized, while the level on the side of the first low-side lobe can reach --18 dB. The antenna was used in Wimax broadband wireless LAN access and displayed good performance. The antenna performance was simulated with Ansoft HFSS. A comparison of the simulation results to that of the experimental results indicate that the two sets of data are quite close in values.
