摘要：
A circularly polarised cut ring microstrip antenna is proposed. The antenna realises circular polarisation and obtains high gain. It is characterised by simple construction and feed mode, and it is not sensitive to the feeding position, which means it is easy to be matched. A study of the different geometric parameters of the antenna and their effect on the performance of the antenna has been conducted. The designed antenna works at about 3.4 GHz, and the results show good performance with a -10 dB return loss bandwidth of similar to 19.6%, a 3 dB axial ratio a bandwidth of similar to 4.2% and a circularly polarised gain of about 10.97 dB. The measured results agree well with the simulated results.
