Abstract (en)

[origin: EP0841715A2] The antenna has two parallel flat segments (3,10,11) of an electrically conductive material short-circuited together along one side edge. These respectively act as an earth reference surface (3) connected to the outer conductor of a coaxial line (4) and connected to the inner conductor of the coaxial line. The smaller surface area segment which is connected to the inner conductor is divided into two partial surfaces (10,11), each of which has a short-circuit connection with the earth reference surface.
