Research output: Contribution to journalArticlepeer-review


A broadband circularly (CP) polarized curl antenna with a simple single feed is presented. The antenna consists of a curled metal strip of about 1.4 wavelengths in length wound into about one turn and mounted above a ground plane with a thick air layer. By using a 50-Ω probe feed along with a vertical feeding metal strip for exciting the curled radiating element, good CP radiation over a wide operating band (with a bandwidth of larger than 6.6%) is achieved, which makes the proposed antenna well-suited for application in the 5.8 GHz band. Details of the proposed antenna design and the experimental results obtained for a constructed prototype are presented.
