A new circularly polarized antenna for GNSS applications
European Conference on Antennas and Propagation, 2017A new and circularly polarized (CP) antenna is proposed for global navigation satellite systems (GNSS) applications. The antenna employs a single feed and two orthogonally elliptical printed dipoles. The dipoles are crossed through a 90° phase delay line

Metasurface-inspired Antenna in Cavity for GNSS Applications [PDF]
12th European Conference on Antennas and Propagation (EuCAP 2018), 2018 International audience; The objective of this work is the development of a miniature antenna integrated inside a rectangular metal cavity. This antenna must cover three of the GNSS systems at the same time (Galileo E1, GLONASS G1 and GPS L1). To this end, the bandwidth must be larger than 60 MHz. A model based on metasurfaces will be presented, as well

GNSS Reflectometry and Applications
2017© Springer International Publishing AG 2018. When positioning with GNSS, multipath signal is a reflected GNSS signal that is a nuisance and as such needs to be eliminated. Whereas this reflected signal on the one hand is a nuisance for positioning, for environmental monitoring purposes, it could be useful in monitoring sea-wind retrieval, seawater ...
