- a central hole recess in the present example, a circular hole recess
- the attachment patch 23 may be provided with circumferentially or circumferentially circumferentially formed essay patch flanks 123, which with a component of the underlying substrate (dielectric) 5 with 14b) or with a component oriented toward the substrate, as shown in FIG. 14a.
- these flanks 123 run perpendicular to the upper side or perpendicularly away from the patch surface 7 'or perpendicularly to the patch surface 7 or the upper side 5a of the dielectric 5 in this case in FIG. 15b ,
- the attachment patch is provided with a peripheral or sectionally angular edge 123 which extends in the manner of a step shoulder running away from the substrate or dielectric 5 and in the variant according to FIG the patch surface 7 is provided to current stu ⁇ fenförmigen paragraph.
- FIG. 17 it is indicated by means of a schematic spatial representation that the attachment patch can not only be generally provided with a laterally angled edge portion 12 but also a plurality of separate or discrete angled portions 123 'can be provided, for example in the form of a hook , Angle etc. are formed and extend with an angle portion 123a of the actual patch surface 7 'of running away and with a subsequent further angle section 123b in plan view of the attachment patch in overlapping arrangement to the patch electrode 7, for example, parallel thereto.
- the dielectric surface formed patch surface 7 and the patch surface 7 'surrounding ring or frame patch 19 may be provided yet another dielectric 47, then arranged on the top and at a distance to the top 47a, the attachment patch 23 and optionally held is.
- the space between the attachment patch 23 and the patch surface 7 underneath and the ring-shaped or frame-shaped patch electrode 19 surrounding the patch surface 7 are therefore in the entire height or in a partial height with an additional one Dielectric 47, so filled a corresponding dielectric layer 47.
- the dielectric layer 47 may, for example, also consist of a foil or include this (eg in the form of a double-sided adhesive film).
- the additional dielectric 47 is formed only at the peripheral edge and is fixed in the surface section 5c on the lower dielectric, firmly bonded thereto, for example adhesively bonded or formed together, in which neither the central patch 7 nor the frame patch 19 is formed is.
- any modifications may be provided in which the additional dielectric 47 is indeed formed like a frame, but at least partially covers the frame patch 19 as well as the central patch 7 with.
- FIGS. 19a and 19b a further modification is shown with reference to FIGS. 19a and 19b.
- the attachment patch 23 is preferably provided with a circumferential or section-wise edge section 23 a, over which the attachment patch 23 can optionally also be held relative to the ring or frame patch 19.
- the peripheral edge 23a is galvanically connected to the ring-shaped or frame-shaped patch 19, so that here only a capacitive coupling between the centrally provided patch electrode 7 and the attachment patch 23 is provided.
- the connection is virtually the reverse of the variant according to FIG. 19a.
- the attachment patch 23 is galvanically connected to the central patch electrode 7.
- the attachment patch is provided only in a partial area of a ring-shaped or frame-shaped section 23b raised in relation to the plane of the central patch 7, which is galvanically connected to the central patch electrode 7 via an angle section 23c, so that here a capacitive coupling is only given between the ring-shaped or frame-shaped attachment patch 23 and the ring-shaped or frame-shaped patch electrode 19.
- the attachment patch 23 may be formed as a continuous metal sheet with the base portion provided within the angular projection 23c, which is connected over its entire surface and thus galvanically connected to the patch electrode A.
- the attachment patch 23 may be formed as a stamped and folded metal sheet, which also fulfills supporting function in this respect.
