Abstract
An antenna device for emitting and/or receiving electromagnetic radiation, such as radar radiation in a car radar apparatus is provided. Sweeping is realized by means of a fixed feeder and a rotatable reflector. The reflector is driven by a drive motor and its motion is monitored by a tachometer. The drive motor and the tachometer are constituted by so-called flag motors which are mutually motionally coupled to each other by mechanical means.
