摘要
将多个单元天线进行合理的布局,组成天线阵列,加上合理的信号处理算法处理,能够有效地提高通信系统的抗干扰性能。分别介绍了阵列的总体设计,对阵列性能相关的阵元选择以及阵元相对位置详细讨论,并推导出4元天线阵的阵元间距和阵元间夹角的具体数值。分析了阵列的性能,尤其是阵元间的互耦影响,并给出了降低互耦的方法,通过测试验证了天线阵列的性能。
Several antenna elements are put together,and a array antenna is constituted.The array antenna can improve anti-interference capability of communication system by reasonable signal processing algorithm.This paper introduces the total design of the array antenna,including the selection and the relative position of antenna elements,and gives the distance and inclination between the four elements.The performances are analyzed in detail,especially reducing the mutual coupling influence between elements,the method how to reduce it is given.The simulations results proves the efficiency of the array antenna.
