Abstract
A diplexer for a homodyne FMCW-radar device, which is distinguished by small dimensions of its hollow conductor structure and therefore can be manufactured simply and cost effectively. The hollow conductor structures of the diplexer can be cut out from two half shells, and the latter joined to form the diplexer. Various materials provide options for the material of the half shells.

1-10. (canceled)
A diplexer for a homodyne FMCW radar device, comprising:
- two closely adjoining, parallel, hollow conductor channels having horizontal polarization and terminal hollow conductor gates;
- a coupling zone in an opening in a partition for connecting said hollow conductor channels;
- and
- depressions located in the region of said coupling zone and arranged perpendicular to said hollow conductor channels,
- wherein:
- a ratio of the dimensions of said hollow conductors channels to the dimensions of said coupling zone and said depressions is so selected that the diplexer displays a broadband behavior and enables propagation of an H20 wave in said coupling zone;
- at said terminal hollow conductor gates have transitions to the transmitter and receiver connected to the diplexer provided, which transitions are so embodied in position and form that they support the desired broadband behavior;
- and
- the diplexer is manufactured from two symmetric half shells.
