Abstract

An antenna for a radar unit for level measurement has a dielectric rod radiator for radiating microwaves in a main radiation direction. A coupling sleeve is provided with an external thread for installation by screwing into a holder opening. The coupling sleeve contains an at least partially approximately hollow cylindrical inner part made of dielectric material that projects in the main radiation direction out of coupling sleeve. A hollow guide system includes an HF coupling device and hollow guide tube that is received in an inner part. As viewed in the main radiation direction, the rod radiator is located releasably or permanently at the forward end of the inner part.
