A broadband circularly polarized cross-dipole antenna for GNSS applications
Loughborough Antennas and Propagation Conference, 2015A broadband circularly polarized (CP) cross-dipole antenna is proposed for GNSS applications. The antenna has a very simple structure and a small size but has a very broad impedance bandwidth from 1.15 to 1.75 GHz (a fractional bandwidth of 41.4%) for ...

Antennas for multi-mode GNSS applications
2012 IEEE Asia-Pacific Conference on Antennas and Propagation, 2012This paper introduces multi-mode antennas for an integrated GNSS receiver, covering GPS, Glonass, Compass and Galileo systems. It presents several kinds of multi-mode GNSS antennas, including microstrip and helix antennas. In each part, some practical and novel designs are presented, such as multi-layer microstrip antennas, slotted patch antennas ...

New antenna design for GNSS application
2015 International Siberian Conference on Control and Communications (SIBCON), 2015A new radiating element design of the slot stripline leaky-wave antennas with right-hand circular polarization is proposed for high-accuracy positioning using Global satellite navigation signals (GNSS) GPS (L1/L2) and GLONASS (L1/L2/L3). Technical characteristics of the antenna with the new radiator have been studied.

Dual-Band Circularly Polarized Annular-Ring Microstrip Antenna for GNSS Applications
IEEE Antennas and Wireless Propagation Letters, 2013A dual-band circularly polarized antenna fed by four apertures that covers the bands of GPS (L1, L2, L5), Galileo (E5a, E5b, E1, E2, L1), and GLONASS (L1, L3) is introduced. A lotus-shaped aperture is added to optimize the coupling between the microstrip
