Abstract
This communication presents a single-feed ultra-wideband circularly polarized (CP) antenna with high front-to-back ratio (FBR). The antenna is composed of two orthogonally placed elliptical dipoles printed on both sides of a substrate. To realize high front-to-back ratio, a novel composite cavity is also proposed and integrated with the presented crossed dipoles, which effectively reduces the back-lobe of the crossed dipoles. Simulation results are in good agreement with measured results which demonstrate an impedance bandwidth from 0.9 to 2.95GHz (106.5%) and a 3-dB axial ratio bandwidth from 1 to 2.87GHz (96.6%). The measured FBR is about 30dB across the whole GNSS band. Compared with other reported single-feed wideband CP antennas, the antenna has advantages such as a wider CP bandwidth and lower back-lobe radiation.
