Abstract
A radar level gauge system comprising: a transceiver; an antenna assembly for arrangement at an opening in a tank wall for radiating a transmit signal vertically towards the product in the tank, and to return a reflection signal resulting from reflection of the transmit signal at a surface of the product; and processing circuitry for determining the filling level based on the transmit signal and the reflection signal. The antenna assembly comprises: a non-plastic dielectric antenna body having a convex surface facing away from an interior of the tank and a planar surface facing the interior of the tank, when the antenna assembly is arranged at the opening in the tank wall; and a feed arranged to direct the transmit signal towards the convex surface of the non-plastic dielectric antenna body.
