A two-layered wideband single-fed circularly polarised (CP) antenna is presented by the authors. A single-fed corner-truncated square patch with four identical rectangular matching branches acts as a bottom-driven patch to generate CP radiation. To broaden the 3-dB axial ratio (AR) bandwidth, a similar patch with a larger size is loaded atop the driven patch as a parasitic patch. The measured results show that the proposed CP antenna has a 17.9% impedance bandwidth from 2.13 to 2.55 GHz and an 11% 3-dB AR bandwidth from 2.15 to 2.4 GHz, respectively. The measured total gain is 7.1 dBic. The results indicate that the proposed antenna is a good candidate for Wireless Local Area Network band applications.
