Abstract: A vehicle body has a plurality of flat and rod-shaped synthetic plastic elements, and a plurality of antennas connected with the synthetic plastic elements for reception and transmission of various frequencies, the synthetic plastic elements at least partially being provided with surfaces and tracks of a differently thick metal coating, the metal coating being structured so that a selection of the antennas for identical or different frequencies and ground reference surfaces as well as regions with screening action are provided, and depending on an operational frequency and a required radiation diagram, radiations with various operational principals being produced, and the surfaces which act for one frequency as radiators for other frequencies belonging to a ground potential, the antennas and ground reference surfaces produced by a structuring as well the regions with screening action being distributed over synthetic plastic elements, the synthetic plastic elements for a predetermined antenna principle being m

Abstract: The invention is a line plug connector for transmitting electrical energy between a cable having a ground conductor and a center conductor, and printed circuit board. The cable end of plug connection is formed by a cable plug having an external conductive sleeve for connection to the ground conductor of the cable, and a center conductive sleeve for connection to the center conductor of the cable. The plug connects to least one elongated tab formed by a plurality of slots on a peripheral edge of the circuit board. In addition on the circuit board is a plurality of metal contacts formed over a portion of the circuit board adjacent to the slot openings.

Abstract: A flat antenna for mounting on windowpanes of motor vehicles reduces the dimensions of the mass reference area of the mass plane, and the structural height without unfavorably influencing the functions and operating parameters of the antenna. The mass reference area has a trough-like shape, is centrally positioned under an aerial segment, and has conductive coating impermeable to the operating frequency of the antenna. The inside and outside conductors of the coaxial feed cable are connected to the aerial segment and mass reference area shifted to outside the aerial elements and thereby enables a significant reduction in overall dimensions.

Abstract: The flat-topped antenna apparatus includes a GPS antenna, a mobile radio antenna, a common housing for the antennas mounted over a ground plane and coaxial cables (12,13,13a) acting as electrical supply lines for the antennas. The mobile radio antenna includes a metal sheet (6,6',6a) plane parallel to the ground plane and spaced at a distance (A,A') of 0.04 of an average operating wavelength of a mobile radio frequency band from the ground plane. The metal sheet is electrically connected at an input terminal (11) with an inner conductor (10) of one coaxial cable (13,13a) and also with the ground plane via a short circuit element (7,7a). The GPS antenna is above and rests on the mobile radio antenna and includes a dielectric plate (1,1a) provided with a metal layer (3) connected at an input terminal (4) with an inner conductor (10) of another (12) of the coaxial cables.
