A fill level measuring device working with microwaves is provided, with which, with very small inventory cost, many applications having a wide variety of different measuring conditions can be handled. The device includes a modularly assembled antenna, having a cylindrical segment closed at one end. A sending and/or receiving element for microwaves is arranged in the segment. A thread of fixed, predetermined diameter is provided on the open end of the segment. The antenna additionally has a radiating and/or intake element, on whose end facing the segment is provided a thread of the fixed, predetermined diameter. Optionally, the antenna has one or more cylindrical functional elements between the segment and the radiating and/or intake element, which have on both ends, in each case, threads with the fixed, predetermined diameter. The segment, the optional functional elements and the radiating and/or intake element are screwed together by means of the threads.

The invention claimed is: 1. A fill level measuring device working with microwaves and having a modularly constructed antenna, comprising: a cylindrical segment closed at one end, in which segment a microwave sending and/or receiving element is arranged, and on whose open end a thread of fixed, predetermined diameter is provided; a radiating and/or intake element, on whose end facing the segment a thread with the fixed, predetermined diameter is provided; and optionally one or more cylindrical, functional elements situated between said segment and said radiating and/or intake element, wherein: on each of the two ends of said one more cylindrical, functional elements, threads are provided at fixed, predetermined diameter; and said segment, said optional functional elements and said radiating and/or intake element are screwed together by means of said threads. 2. The fill level measuring device as claimed in claim 1, wherein: in the area of two threads screwed together, a welded connection is additionally provided. 3. The fill level measuring device as claimed in claim 1, wherein: further comprising: a functional element serving a spacer piece which enlarges a distance between temperature sensitive components of the fill level measuring device and said radiating and/or intake element. 4. The fill level measuring device as claimed in claim 3, wherein: two or more spacer pieces are provided. 5. The fill level measuring device as claimed in claim 1, wherein: one of said functional element is a process separation. 6. The fill level measuring device as claimed in claim 5, wherein: the process separation is pressure-tight.
