提出了一种通过增加曲折开槽谐振器来增强阵列天线单元间隔离度的方法。首先设计了一款应用于802.11ac(5.17~5.29 GHz)频段移动终端的天线,在其阵列单元间添加一个曲折的开槽谐振器,此谐振器具有带阻特性,能有效降低天线单元间的互耦,增强天线单元间的隔离度,并利用HFSS软件对微带阵列天线进行了仿真与优化。仿真结果显示,增加了开槽谐振器后天线的隔离度增强了11.31 dB,隔离度达到了–29.4 dB,驻波比VSWR小于1.35,S11小于–16 dB,S21达到了–26 dB,满足天线的要求。
A method of increasing the isolation between array antenna elements by adding meander slot resonators is proposed. First of all, an antenna designed for mobile terminals in the 802.11ac (5.17-5.29 GHz) frequency band is designed. A zigzag slot resonator is added between the array elements. The resonator has a band-stop characteristic and can effectively reduce the interference between antenna elements Mutual coupling to enhance the isolation between antenna elements, and the use of HFSS software microstrip array antenna simulation and optimization. The simulation results show that the isolation of the antenna increases 11.31 dB, the isolation reaches -29.4 dB, the VSWR VSWR is less than 1.35, S11 is less than -16 dB and S21 is -26 dB, Request.
