This paper presents a theoretical analysis of the effect of beam scanning and amplitude tapering on the cross‐pol level of sequentially rotated linear arrays composed of circularly polarized patch antenna elements. Arrays of eight elements are considered to illustrate the analysis. Several sequential phase distributions are analyzed in terms of the cross‐pol level cancellation effect over the antenna field of view. These arrangements are analyzed in terms of the location of the maximum cross‐pol peak levels and their values. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 343–350, 2001.
