摘要：

An omnidirectional circularly-polarised patch antenna is proposed. The antenna radiates right-handed circular-polarisation with an average axial ratio of 2.3 dB over a full 360 degrees. A shallow diagonal CPW inset-feed was used to achieve good matching to the back-to-back coupled patches, providing a measured S-11 < -15 dB at the centre frequency. The measured cross-polar performance is better than 13 dB and the realised gain variation is similar to 3 dB in the plane normal to the substrate.
