使阵列天线具有均匀分布并使阵元之间具有恒等相位差的馈电方式之一是借助于巴特勒矩阵。由巴特勒首先提出来的这个矩阵,它包含有N个输入端口和同等数量的输出端口或者辐射单元,当在某一输入端引进一个信号时,即在所有的输出端产生等辐激励,且它们之间具有恒等相位差,这就在空间某一角度方向产生辐射。Allen和Delaney已经应用巴

One of the ways in which the array antenna has an even distribution and such that there is an equal phase difference between the array elements is by means of a Butler matrix. This matrix, first proposed by Butler, consists of N input ports and an equal number of output ports or radiating elements. When a signal is introduced at an input, an isometric stimulus is generated at all outputs and There is an equal phase difference between them, which produces radiation at a certain angle in space.
