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 metalized in two planes located one behind the other with a distance from one another which is operationally important for a corresponding operational principle.
