“…e global navigation satellite systems, such as Global Positioning System (GPS), GLONASS, Galileo, and BDS, have been used in many areas such as navigation, positioning, geographic surveys, time standards, and meteorology. Accuracies on the order of centimeters and millimeters are required in many high precision applications [1,2]. However, multipath error continues to be a major limiting factor in realizing the level of accuracy [3][4][5].…”

This letter presents a wideband antenna for high-precision Global Navigation Satellite System (GNSS) applications. The antenna consists of a pair of improved orthogonal dipoles that are fed by a feed network with Composite Right/Left-Handed Transmission Lines (CRLH-TLs), a polygonal patch, and a reflector. By using improved orthogonal dipole, the beamwidth of the antenna is broadened. The CRLH-TLs is adopted in feed network to obtain outputs with stable phase difference. Experiment results indicate that the antenna has a less than 10-dB return-loss bandwidth in the range of 1.1 to 1.7 GHz, a 3-dB axial-ratio bandwidth from 1.2 to 1.6 GHz, and a larger than 6.37 dBi gain in the whole operating band. The measured results show that the proposed antenna has stable performance in the whole operating band, which means that it is a suitable antenna used for GNSS applications.
