An analytical model of sequentially rotated phased arrays with arbitrary antenna elements is presented. It is applied to different arrays and the improvements of axial ratio bandwidth and copolar directivity are investigated. It is compared to a numerical Method of Auxiliary Sources model to ascertain the accuracy and limitations. © 2007 Wiley Periodicals, Inc.
