Abstract
A radar level gauge system, for determining a filling level of a product in a tank, comprises a transceiver, an antenna assembly, and processing. The antenna assembly comprises a dielectric antenna body having a conical external surface facing an interior of the tank and an internal surface facing away from the interior of the tank, when the antenna assembly is arranged at the opening in the tank wall, and an antenna feed coupled to the transceiver, and configured to propagate the transmit signal towards the internal surface of the dielectric antenna body as electromagnetic waves with convex wavefronts. The internal surface of the dielectric antenna body is shaped to refract the transmit signal from the antenna feed in such a way that the transmit signal propagates towards the surface of the product in the tank as electromagnetic waves with substantially planar wavefronts, following passage through the dielectric antenna body.
