Claim Text:
1. A sensor, for a fill level measuring device for determining the fill level in a container by determining the delay time of high-frequency signals, comprising: a main reflector having an edge region and an inner region; a sub reflector, operatively connected to the edge region of the main reflector via a radome; an inner space encompassed by the radome and the main reflector; and a hollow waveguide which is operatively positioned and connected to the main reflector and has a front end, said front end being oriented toward the sub reflector for coupling electromagnetic waves thereto; the radome and the sub reflector are embodied being integral with each other; and the thickness of the radome is such that it corresponds to a whole-number multiple of one-half the dielectric wavelength of a coupled-in electromagnetic wave, wherein the wavelength preferably corresponds to a wavelength of the W-band, particularly preferably a wavelength of between 77 GHz and 81 GHz.
