Abstract (en)

[origin: EP0948084A2] The antenna element has a planar radiation element (2) in a first plane, a metaled surface (4) in a second plane with at least two slots (5,6) arranged beneath the radiator element and a supply line structure (7,8) in a third plane coupled to the slots. One slot (5) on a radiator element symmetry line (11) and at least one other slot (6) is orthogonal and mirror symmetrical to the symmetry line. The slots are coupled to separate supply lines. The slot running orthogonally w.r.t. the symmetry line is coupled to a supply line, which forms a mirror symmetrical supply branch, at two points (12,13) arranged mirror symmetrically w.r.t. the symmetry line.
