Abstract

An insulating glazing unit includes a spacer which is shaped around the periphery to form a spacer frame and delimits an inner region, a first glass pane, which is arranged on a pane contact surface of the spacer frame, and a second glass pane, which is arranged on a second pane contact surface of the spacer frame, and the glass panes project beyond the spacer frame and form an outer region, which is filled, at least in sections with a sealing element, wherein an RFID transponder is arranged in the outer region or in the outer edge region of the glass panes, and a strip-shaped coupling element is electromagnetically coupled to the RFID transponder.

First claim

1 . An insulating glazing unit, comprising:
at least one spacer which is shaped around a periphery to form a spacer frame and delimits an inner region, a first glass pane, which is arranged on a pane contact surface of the spacer frame, and a second glass pane, which is arranged on a second pane contact surface of the spacer frame, and the first and second glass panes project beyond the spacer frame, and an outer region is formed, which is filled, at least in sections with a sealing element,
wherein
at least one RFID transponder is arranged in the outer region or in an outer edge region of the first and second glass panes,
a strip-shaped coupling element is electromagnetically coupled to the at least one RFID transponder, and
the strip-shaped coupling element projects in sections beyond an end face of the insulating glazing unit along the first glass pane and/or along the second glass pane.

2 . The insulating glazing unit according to claim 1 , wherein the strip-shaped coupling element contains or is made of a metallized polymer film or a self-supporting metal foil.

3 . The insulating glazing unit according to claim 2 , wherein the metallization of the polymer film has a thickness of 10 μm to 200 μm and the metal foil has a thickness of 0.02 mm to 0.5 mm.

4 . The insulating glazing unit according to claim 1 , wherein the strip-shaped coupling element projects in sections beyond the end face of the insulating glazing unit along the first glass pane by an overhang U of 2 mm to 30 mm.

5 . The insulating glazing unit according to claim 1 , wherein the at least one RFID transponder is arranged in the outer region and directly on an outer surface of the spacer or on one of inner surfaces of the first and second glass panes or in a middle of the outer region.

6 . The insulating glazing unit according to claim 1 , wherein the at least one RFID transponder is arranged on an outer surface of one of the first and second glass panes at a distance of at most 10 mm from an adjacent end face of the respective glass pane and/or wherein the at least one RFID transponder is arranged on an end face of one of the first and second glass panes.

7 . The insulating glazing unit according to claim 1 , wherein the strip-shaped coupling element is arranged
within the sealing element in the outer region, on an outer side of the outer region, on at least one end face of the first and second glass panes, and/or on an outer side of the first and second glass panes.

8 . The insulating glazing unit according to claim 1 , wherein a distance A between a dipole antenna of the at least one RFID transponder and the strip-shaped coupling element is from 0 mm to 10 mm.

9 . The insulating glazing unit according to claim 1 , wherein the strip-shaped coupling element is arranged in sections congruently over the at least one RFID transponder.

10 . The insulating glazing unit according to claim 1 , wherein the at least one RFID transponder includes or consists of a dipole antenna with a first antenna pole and a second antenna pole.

11 . The insulating glazing unit according to claim 10 , wherein the strip-shaped coupling element covers exactly one of the first and second antenna poles and projects beyond the one of the first and second antenna poles on the side facing away from the other one of the first and second antenna poles.

12 . The insulating glazing unit according to claim 10 , wherein one edge of the strip-shaped coupling element has, in the projection, an offset V from a center of the dipole antenna of −20% to +20% of a half wavelength lambda/2 of an operating frequency of the at least one RFID transponder.

13 . The insulating glazing unit according to claim 10 , wherein one edge of the strip-shaped coupling element has, in the projection, an offset V from a center of the dipole antenna at an operating frequency of the at least one RFID transponder in the UHF range of −30 mm to +30 mm.

14 . The insulating glazing unit according to claim 1 , wherein the strip-shaped coupling element has a length L parallel to a direction of extension of the dipole antenna greater than or equal to 40% of a half wavelength lambda/2 of an operating frequency of the dipole antenna.

15 . The insulating glazing unit according to claim 1 , wherein the strip-shaped coupling element has a length L parallel to a direction of extension of the dipole antenna greater than or equal to 7 cm.

16 . A glazing, comprising:
a frame consisting of a metal first frame element, a metal second frame element, and a polymeric third frame element connecting the metal first and second frame elements at least in sections, and an insulating glazing unit according to claim 1 arranged in the frame,
wherein the strip-shaped coupling element is galvanically or capacitively coupled in at least one coupling region with one of the metal first and second frame elements.

17 . The glazing according to claim 16 , wherein the metal engages around the end faces of the insulating glazing unit and, at the same time, covers the at least one RFID transponder(s) in a through-vision direction through the first and second glass panes.

18 . A method comprising identifying a glazing according to claim 16 with the at least one RFID transponder.

19 . The insulating glazing unit according to claim 1 , wherein the outer region is filled completely with the sealing element.

20 . The insulating glazing unit according to claim 2 , wherein the strip-shaped coupling element is made of aluminum, an aluminum alloy, copper, silver, or stainless steel.
