Abstract: Disclosed is a collision warning unit configured to emit a detection signal into a surrounding area and to receive at least one signal component reflected at an object in the surrounding area, and, depending on the received signal component, to output a collision warning signal. The collision warning unit has a UWB (ultra-wideband) radar for transmitting the detection signal and receiving the reflected signal component.

Abstract: A one-piece antenna module, has at least one outside receiving and/or transmitting antenna element under an outer cover. The one-piece antenna module has an antenna box, which has no or few inside internal antennas and which surrounds the electronic circuits that interact with the antenna elements. The outer cover is detachably fastened to the antenna box and can be attached so as to protrude from an opening in the vehicle roof. The antenna box is closed on all sides and can be attached below the vehicle roof by a metal top side. The metal closed top side has feed-throughs for the outside antenna elements. The outside antenna elements in the outer cover are electrically coupled to the circuits inside the antenna box closed on all sides by the feed-throughs. Thus, a compact installation part is obtained, which provides complete shielding between an antenna part and a transceiver part.

Abstract: A fin-shaped multi-band antenna module, e.g., for vehicles, includes an antenna printed circuit board and a plate arranged thereupon. In a lower region the plate is mechanically connected to the antenna printed circuit board. A first monopole extends in an essentially vertical direction on the plate and is connected to the antenna printed circuit board in a lower region by a feed point. The first monopole is inductively extended in the vertical direction in an upper region of the first monopole in order to enable transmission and reception of electromagnetic waves in a lower telephone frequency range.

A dipole is provided on each electrically conductive structure. The dipoles form a first U-shaped dipole structure on each of the two substrate plates. On an upper edge region of each of the substrate plates, the dipole structure has a line element, and on the lateral regions of the substrate plate, the dipole structure has electrically conductive limbs. The electrically conductive structure has a monopole arranged asymmetrically to the dipole structure for respectively feeding the dipole.

Abstract: A multiband shark fin antenna for a vehicle may include at least one transmitting and one receiving antenna element from the group consisting of AM/FM antennas, telephone and RKE antennas, GPS antenna, SDARS antenna, stacked patch antenna, DAP antenna, WLAN antenna, WIMAX antenna or DRM antenna. The antenna elements are disposed beneath a joint shark fin-shaped outer cover on the exterior of the vehicle. On the inside, the shark fin-shaped outer cover includes an antenna circuit board having the antenna elements disposed thereon. Electronic adjustment or amplifier circuits including a transceiver, tuner or receiver are disposed on both the upper and lower faces of the antenna circuit board. Shielding plates, which shield the adjustment or amplifier circuits with respect to the antenna elements, are disposed on the upper side of the antenna circuit board.
