Abstract: The Beidou-3 satellite navigation system was officially opened in 2020. While bringing high-performance services to people around the world, the navigation system requires well-designed beidou antennas. In this paper, we propose a wideband circularly polarized high performance beidou antenna. The antenna realizes wideband circularly polarized radiation through a four-port sequential feed network, and the phase imbalance of the feed network from 1.05 to 1.8 GHz is less than ±7°. The manufactured antenna demonstrated a return loss of more than 13 dB, and an axial ratio of 3 dB over the entire global navigation satellite system (GNSS) frequency band. The RHCP gain of the proposed antenna is greater than 4 dB in the GNSS low frequency band, and can reach more than 7.1 dB in the high frequency band. Its dimensions are 120 mm× 120 mm× 20 mm, (0.54 × 0.54 × 0.09) , where is the wavelength of the center frequency. The developed antenna connected to a GNSS receiver tracked 12 Beidou satellites with ratios of GNSS signals greater than 30 dB. Such a high-performance antenna provides a basis for high-quality positioning services.
