Reflective Butler Matrices.

Abstract:

A conventional Butler matrix can be modified to achieve a network which is symmetric about an axis midway between the input and output lines. Such a Butler matrix network can be cut in that plane of symmetry so that the input and output ports are identical. In this manner, the half-matrix corresponds to a reflection-type system in which the feed positions are in the aperture region. This report describes the modifications which symmetrize the Butler matrix and the method for cutting the network on the symmetry plane so as to achieve a reflective matrix. A computer program which generates and plots this network is presented. Author
