1. A diversity antenna for connection to a receiver located on a conductively framed dielectric surface substantially assembled from rectangular partial surfaces in a body of a motor vehicle, comprising:

  • an antenna conductor in a form of a wire disposed parallel to at least a portion of the conductive frame of the dielectric surface with a spacing of less than one fourth of the width of the existing dielectric surface, wherein said antenna conductor includes at least one interruption site defining a pair of antenna connection terminals and forming at least two antennas; and

    at least one two-pole electronically controllable impedance network serially integrated in said at least one additional interruption site, wherein a position of said at least one interruption site with said pair of antenna connection terminals and a position of said at least one additional interruption site are selected so that a plurality of antenna signals available at different adjustments of said controllable impedance network are adequately decoupled to select a most suitable signal selected from said plurality of antenna signals.
