Abstract

The relates to a measuring device neck of a radar based, fill level measuring device for determining a fill level profile (L(α,β)) of a fill substance. In the measuring device neck, the waveguides for contacting the antenna arrangement are aligned along a contour (k1, k2), which surrounds the device neck axis radially symmetrically and adjoins the measuring device neck. Such is advantageous, since the waveguides can be made together as a monolithic, basic body, which can be inserted easily into the measuring device neck. Furthermore, the arrangement of the waveguides in the measuring device neck favors the thermal management in the transmitting/receiving electronics of the fill level measuring device, since its thermally critical radar chips can be spaced maximally from one another.
