ABSTRACT:
An improved dual-polarized antenna arrangement has four antenna element devices each with a conductive structure between opposite antenna element ends. Those antenna element ends of two adjacent antenna element devices adjacent to one another are, in each case, isolated from one another for radio frequency purposes. Those antenna element ends of two adjacent antenna element devices located adjacent to one another in pairs form feed points, and the antenna element devices are fed at least approximately in phase and approximately symmetrically between the respective opposite feed points.
