Development of an efficient code for rapid analysis of beam forming networks

Abstract

The authors describe the method and the numerical technique to analyze feed networks for beam forming and phased array antennas. The goal of the effort is to theoretically analyze and numerically develop a technique which can be used in fast analysis of beam forming networks. The examples chosen are three, six, and eight networks, but the technique is general enough to handle N /spl times/ N networks. Consideration is given to the development of a CAD (computer-aided design) tool to get the output of the network when all characteristics of the elements as well as all interconnections are assumed to be known. Corresponding radiation patterns can be obtained when the outputs are connected to radiating elements. Two numerical methods are considered, the event driving method and the matrix multiplication method. The first has been shown to be more efficient than the second.<>
