Analysis of element characteristics of finite phased arrays using matrix manipulations

Abstract

In this paper, the method of moments is employed to analyze finite phased arrays of radiating slots fed by rectangular waveguides. Also, the relationships among magnetic currents, reflection coefficients, and coupling coefficients are analyzed numerically using basic matrix manipulations. Active patterns of elements in phased arrays, and their relationships with reflection coefficients and magnetic currents are discussed. Numerical results of reflection coefficients compared with existing measured and theoretical results and a fairly good agreement is obtained.
