An antenna system comprises at least two dipole antennas (6) constituting an antenna module and is placed above and parallel with a common, artificial ground plane (5) in the form of an electrically conducting plate, for instance the bottom of a metal box (2). The dipoles (7) and the feed lines (8, 9, 10, 11) are designed as air dielectric strip-lines and are configured in one piece of a homogeneous material and extend mechanically and electrically in an uninterrupted manner from the dipoles to the antenna connector. The parts configured in one piece are produced by punching out sheet metal, and after suitable bending the parts are inserted in corresponding openings (16) in the ground plane (5).
