TRANSPONDER COMPRISING A BOOSTER ANTENNA
A transponder including a first antenna and an integrated circuit on a chip electrically connected to the first antenna. A second antenna is physically separated from the first antenna. The second antenna is close enough to the first antenna so that the second antenna can couple with the first antenna. One of the first antenna and the second antenna is transferable with respect to the other antenna so that the coupling between the antennas is preventable.
1 - 7 . (canceled)
8 . A transponder, comprising:
a first antenna;
an integrated circuit on a chip electrically connected to the first antenna; and
a second antenna that is physically separated from the first antenna, the second antenna being in proximity to the first antenna such that the second antenna can couple with the first antenna to boost a communication distance of the first antenna, and one of the first antenna and the second antenna is arranged to be transferable with respect to the another of the first antenna and the second antenna such that coupling between the first antenna and the second antenna can be intentionally prevented.
9 . The transponder according to claim 8 , further comprising:
a substrate having a surface on which the first antenna, the integrated circuit on the chip and the second antenna are situated, wherein the first antenna and the second antenna are separated from each other by a borderline.
10 . The transponder according to claim 7 , wherein the borderline comprises a perforation.
11 . The transponder according to claim 8 , wherein the first antenna and the integrated circuit on the chip are situated on a surface of a substrate, and wherein the second antenna is situated inside or on an outer surface of a housing of an EAS unit.
12 . The transponder according to claim 8 , wherein the first antenna and the integrated circuit on the chip are situated inside a watertight shell, and wherein the second antenna is integrated in a garment.
13 . The transponder according to claim 8 , wherein the first antenna and the integrated circuit on the chip are situated on a surface of a substrate, and wherein the second antenna is integrated in a textile or film material.
14 . The transponder according to claim 8 , wherein the first antenna and the integrated circuit on the chip are integrated in a textile or film material, and wherein the second antenna is situated on a surface of a substrate.
