Abstract

A new wideband 2 × 2 patch antenna array operating at 5.8 GHz with an out‐of‐line series feed is presented. Input impedance bandwidth and axial ratio bandwidth are shown to be significantly increased for this new array, which employs a sequential rotation of series‐fed, circularly polarised, aperture‐coupled radiating elements. The array also maximises the available space on the feed substrate for microwave circuitry. A VSWR 2:1 bandwidth of 22.8% and a 3‐dB axial ratio of 17.5% are confirmed by full‐wave simulation and experimental measurement. © 2004 Wiley Periodicals, Inc.

## Abstract In this article, a novel wideband cularly‐polarized serial rotated 2 × 2 circular patch antenna array is presented. The patches are excited sequentially by a broadband feed network. It is found that the antenna array can deliver a measured impedance bandwidth of 46.6% for SWR < 2, 3‐dB

## Abstract By adopting a sequential rotation technique with the use of an L‐strip microstrip line to feed the proposed patch antenna array, a broadband design for circular polarization (CP) is proposed and experimentally studied. The impedance bandwidth and 3‐dB axial‐ratio bandwidth of the circul
