Abstract
In this paper we present the antenna developed for the Sentinel-1 SAR, Sentinel-2 optical, and Sentinel-3 radar altimeter missions. These earth observation ESA missions require GNSS to localise measurements and to determine sea levels with cm accuracy as part of a radar altimeter system. A dual frequency GNSS antenna with good coverage, low loss and very low interference has been developed and tested. Excellent back radiation suppression is achieved within a volume of only 200 mm in diameter.
