Patent attributes
A radar level gauge system, comprising a transceiver; an antenna arrangement configured to transmit an electromagnetic transmit signal from the transceiver, and to return an electromagnetic reflection signal resulting from reflection of the transmit signal at a surface of the product back towards the transceiver; and processing circuitry. The antenna arrangement comprises: a dielectric antenna body having a transmit signal receiving surface to receive the transmit signal from the transceiver, a convex transmit signal emitting surface configured to direct the transmit signal towards the product following passage of the transmit signal through the dielectric antenna body, and a side surface connecting the transmit signal receiving surface and the transmit signal emitting surface; and an electrically conductive antenna housing covering at least a portion of the side surface of the dielectric antenna body. The dielectric antenna body is arranged to conductively separate the transceiver from the conductive antenna housing.
