  • an upper parasitic patch arrangement 13 is provided, similar to that described with reference to FIG. 4 and the other exemplary embodiments.
  • the further patch antenna B has at its circumferential side walls, ie at its outer peripheral surfaces 105d metallizing sections, so metallization gene 253d, which extend in this embodiment only in a partial height (but can also be formed in the entire height of the further patch antenna B).
  • the metallizations 253d extend at a height which, when viewed exactly from the side, projects beyond the encircling edge 13 'of the upper patch arrangement 13 at least at a partial height, but also ends below it.
  • This metallization 253d can also have sections of different height over the circumferential area, with interruptions, in some cases with connections to a metallization formed on the underside of the further patch antenna B, etc. Further restrictions are therefore likewise not given here.
  • the parasitic patch arrangement 13 in question can be provided with flattenings, recesses or so-called omissions 13 "at two opposite corner regions, as already indicated in plan view in FIG. 3 and in a three-dimensional view in FIG
  • the peripheral edges, walls or webs 53d are also interrupted at these corner regions by the gaps 13 ", the further patch antenna B located in this box-shaped or box-like parasitic patch element 13 can protrude outward at these corner regions via the thus created opening regions 13a between two adjacent edge sections 53d, so that the circumferential edge 105d of the further patch antenna B becomes visible.
