Abstract

A carrier structure including a carrier, an antenna structure on the carrier and a reception region designed for removable reception of an RF chip. The reception region is arranged relative to the antenna structure in such a way that inductive coupling to the antenna structure is enabled when the RF chip is arranged in the reception region. An inductive blocking element on the carrier blocks communication with the RF chip using the antenna structure in a first position of the inductive blocking element. In a second position of the inductive blocking element, the inductive blocking element enables communication with the RF chip using the antenna structure.

First claim

1 . A carrier structure, comprising:
a carrier; an antenna structure on the carrier; a reception region designed for removable reception of an RF chip, the reception region being arranged relative to the antenna structure in such a way that inductive coupling to the antenna structure is enabled when the RF chip is arranged in the reception region; and an inductive blocking element on the carrier, which in a first position of the inductive blocking element blocks communication with the RF chip using the antenna structure and in a second position of the inductive blocking element enables communication with the RF chip using the antenna structure.

2 . The carrier structure as claimed in claim 1 , wherein the inductive blocking element contains an electrically conductive surface, in particular a metal surface.

3 . The carrier structure as claimed in claim 1 , wherein the inductive blocking element includes an electrically closed turn, which in the first position is positioned so that it blocks communication with the RF chip using the antenna structure and in a second position of the inductive blocking element enables communication with the RF chip using the antenna structure.

4 . The carrier structure as claimed in claim 3 , wherein the inductive blocking element has a single low-resistance closed turn, electromagnetic energy is drawn from the antenna structure in the first position.

5 . The carrier structure as claimed in claim 1 , wherein the inductive blocking element has a half-turn, which is electrically separated from a second half-turn in the first position and is electrically connected thereto in the second position.

6 . The carrier structure as claimed in claim 1 , further comprising:
a reception apparatus for a cellphone.

7 . The carrier structure as claimed in claim 1 , wherein the antenna structure has two respectively spiral antenna parts.

8 . The carrier structure as claimed in claim 7 , wherein the antenna parts are electrically connected to one another by a connecting line.

9 . The carrier structure as claimed in claim 1 , wherein the carrier is folded in the first position, while the carrier is not folded in the second position.

10 . The carrier structure as claimed in claim 1 , wherein the carrier is cellulose-based.

11 . The carrier structure as claimed in claim 1 , wherein the reception region is adapted to receive a chip card, which has the RF chip.

12 . An envelope comprising an inductive blocking instrument operable to block an antenna structure that has been introduced into the envelope.
