Analysis of element characteristics of finite phased arrays using matrix manipulations

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