Abstract: A diversity antenna for the meter and decimeter wave ranges installed on a conductively framed dielectric surface in the body of a motor vehicle and substantially assembled from rectangular part surfaces, for example in a roof cutout or trunk with a dielectric trunk lid. A substantially wire-shaped antenna conductor is installed parallel with the conductive frame and spaced from a part thereof of the dielectric surface less than one fourth of the width of the dielectric surface. The wire-shaped antenna conductor has an interruption site which define a pair of antenna connection terminals. A two-pole, electronically controllable impedance network is incorporated in series in at least one additional interruption site.
