A wideband circularly polarized 2 × 2 sequentially rotated patch antenna array

Abstract

Abstract A wideband circularly polarized 2 × 2 sequentially rotated patch antenna array is presented. This array applies the wideband circularly polarized elements to the sequential rotated feeding to realize wide bandwidth by a simple structure. A measured −10‐dB return loss bandwidth of 102% and an AR < 3‐dB bandwidth of 43.7% are obtained. © 2007 Wiley Periodicals, Inc.
