摘　　要：采用可以把相位差信息转换为强度信号的简易天线(LSMC天线),实验研究了互耦对天线输出信号的影响,结果表明:在电磁波不同的到达方向角条件下,天线之间均存在明显的互耦;两天线距离大于波长一半或重叠面积比例小于0.2时,它们间的互耦变得很弱.在实际应用中,可以根据本文结果对LSMC天线的间距和重叠面积调整,以减弱天线间的互耦.Simple antenna（LSMC antenna） that can transform phase difference information into an intensity signal was used in this work.The influence of mutual coupling on antenna output was investigated.Data showed significant mutual coupling between antenna for different direction of Arrial of electromagnetic wave.With spacing between two antenna more than half a wavelength or with the overlapping ratio being less than 0.2,mutual coupling became very weak.For direction of arrial measurement,the use of LSMC antenna could effectively reduce mutual coupling.
