Abstract
The invention consists of a flat mobile antenna for frequencies in the GHz-range. The flat antenna comprises first and second partial surface segments made from electrically conductive material, and separated from each other by a gap. The antenna also comprises a ground plane surface spaced substantially parallel to, and arranged below the first and second partial surface segments. The first and second partial segments are connected to the ground plane surface by two short-circuit-like conductors at a right angle. Connected to the second partial segment is a coaxial antenna cable having a center conductor and an outer shield conductor. The outer shield conductor is connected to the ground plane surface, and the center conductor is connected to the second partial surface segment at an input feed point, forming a galvanic connection. Connected to and extending out on either side of the second partial surface segment are short strip-like segments or tabs which are connected to the center conductor of the antenna coaxial cable to serve to match the impedance in the feed point.
