摘要
分析阵列天线的互耦机理,利用电磁散射理论研究阵列天线的散射特性,得到阵列天线的散射矩阵,并根据散射矩阵中的实际物理意义,将矩阵进行分解,推导出阵列天线的互耦补偿公式,避免了复杂的计算,并在实际测试数据的基础上,利用提出的算法进行互耦补偿,验证了该算法的有效性。
The process of mutual coupling in array antennas is investigated. With the help of scattering matrix in array antennas, a mutual coupling compensation algorithm is derived, and verified with the measured data of a 64 - element planner array. The experiment results show that this method could avoid time-consuming complex calculation, and can be applied in real application.
