Design and Performance Evaluation of a 4*4 Butler Matrix Feeding Network Antennas with 26 GHz

Abstract

A simulation of the matrix of Butler without network of antennas was made to obtain the level-headedness in amplitude and in phase which must be distributed to every radiant element and determine the radiation pattern. Then, we shall proceed to a global simulation of the matrix with its network of antennas to calculate the parameters S of reflection and insulation of the ways of entrance and see an approach to radiation pattern of all of matrix.
