Abstract

A compact radar device that can be produced with little complication has at least one cavity (3) with a radiation element (10) disposed therein and a shielded chamber (2) for electrical circuits (4). A housing (1) is designed in such a manner that it defines both the shielded chamber (2) for the electrical circuits (4) and the at least one cavity (3) for the at least one antenna radiation element (10). A printed board (5) carries the electrical circuits (4) and is inserted into the housing (1) between the two chambers (2, 3) as a shielding partition. The antenna radiation element (10) is electrically coupled to the two conductor arms to a feed network on the printed board (5) via contact pins (16, 19).
