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.
