A wideband single-fed circularly-polarised patch antenna is presented. It is implemented by using a 3D meandering strip to feed a square patch antenna. This antenna has very good circular-polarisation characteristics with wide axial ratio bandwidth, stable radiation patterns and high antenna gain across the operating bandwidth. Results show that the proposed antenna has an impedance bandwidth (SWR2) of 25.2% (2.18–2.81 GHz), an axial ratio bandwidth (AR3 dB) of 22.4% (2.18–2.73 GHz) and a peak gain of 8.2 dBic.
