    摘要: This invention concerns a repeater jamming transmitter (2), and a casing arrangement with repeater jamming transmitter. The repeater jamming transmitter (2) comprises transmitter antenna (7), receiver antenna (8) and electronics part (10) with amplifier and control circuits. In order to avoid self-oscillation caused by leakage between the transmitter antenna (7) and the receiver antenna (8) and to maintain the isolation a special connection arrangement (7,8,10) is included in the repeater jamming transmitter. By means of the connection arrangement the amplification of the repeater jamming transmitter can be increased without self-oscillation arising.

    摘要: 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.
