Abstract
A radar level gauge system, comprising a transceiver; an antenna; a feed-through connecting the transceiver and the antenna; and processing circuitry coupled to the transceiver. The feed-through comprises a first waveguide section comprising a dielectric plug sealingly arranged in a cylindrical first hollow conductor section having a diameter selected for single mode propagation; a second waveguide section arranged between the transceiver and the first waveguide section and comprising a cylindrical second hollow conductor section having a second diameter selected for single mode propagation, a third waveguide section arranged between the antenna and the first waveguide section comprising a cylindrical third hollow conductor section having a third diameter selected for single mode propagation; a first impedance matching waveguide section arranged between the first waveguide section and the second waveguide section, and a second impedance matching waveguide section arranged between the first waveguide section and the third waveguide section.
