摘要
运用寄生贴片降耦方法,提出了一种简单但高效率的减小倒置背腔式缝隙天线耦合的结构,通过放置矩形寄生贴片降小耦合,与无附加结构的天线相比,在反射系数小于-10d B的3.2%(中心频率为12GHz)带宽范围内互耦降低了6d B,天线的方向图得到了改善,端射方向的能量减小。分析了腔体模式对天线耦合的影响。
A simple but high efficient approach of reducing the mutual coupling for inverted cavity-backed slot antennas is presented. By inserting rectangular patch between two coupled slot antennas, the mutual coupling reduction of 6d B is achieved in the bandwidth of 3.2%(at the central frequency of 12GHz) with reflection coefficient less than-10 d B. Meanwhile, radiation patterns are improved and end-fire radiation is reduced. And then the effect of cavity mode on mutual coupling is analyzed.
