Abstract
A compact disc coupled to a wireless communication device comprises the disc with a metalized outer portion, a wireless communication chip and a pair of tabs. The first tab may capacitively couple the wireless communication chip to the metalized portion of the disc. The second tab may be positioned in an inner portion of the disc with a gap delimited by the metalized portion and the second tab. A slot antenna is thus formed through which the wireless communication device may communicate. Wireless communication chip allows disc to be interrogated and identified for a variety of purposes, including, but not limited to security, advertising and promotion, and issuing of related coupons to customers for subsequent purchases.
Claims66
A disc having a metal region for the storage of data thereon coupled to a wireless communication device,
- wherein the disc comprises an outer metalized portion and the outer metalized portion includes the metal region;
- and
- wherein the wireless communication device comprises:
- a wireless communication chip;
- a first tab positioned on the outer metalized portion;
- a second tab spaced from the outer metalized portion by a gap with the wireless communication chip positioned between the first tab and the second tab;
- and
- a stub extending from the second tab across the gap;
- and
- wherein the metal region of the disc is used as part of an antenna for the wireless communication device.
A method of communicating information related to a disc having a metal region for the storage of data, comprising:
- positioning a wireless communication device on the disc, wherein the disc comprises an outer metalized portion and the outer metalized portion includes the metal region;
- coupling a first tab of the wireless communication device to the outer metalized portion;
- positioning a second tab of the wireless communication device on an inner portion of the disc and spaced by a gap from the outer metalized outer portion of the disc;
- extending a stub from the second tab across the gap;
- coupling the metal region as part of an antenna for the wireless communication device;
- and
- interrogating the disc with an interrogation reader.
A method of communicating information related to a disc, comprising:
- positioning a wireless communication device on the disc by:
- coupling a first tab of the wireless communication device to a an outer metalized outer portion of the disc;
- and
- positioning a second tab on an inner portion of the disc and spaced by a gap from the outer metalized outer portion of the disc;
- and
- positioning a wireless communication chip between said first and second tabs such that the gap between said outer metalized portion and said second tab acts as a slot antenna;
- and
- interrogating the disc with an interrogation reader.
A wireless communication device, comprising:
- a wireless communication chip;
- a first tab coupled to a an outer metalized outer portion of a disc and electrically connected to said wireless communication chip;
- and
- a second tab adapted to position configured to be positioned on an inner portion of the disc and electrically connected to said wireless communication chip;
- and
- wherein said second tab adapted is configured to be spaced from the outer metalized portion so as to form a slot antenna therebetween.
A disc having data stored thereon coupled to a wireless communication device, wherein said disc comprises an outer metalized portion and said wireless communication device comprises:
- a wireless communication chip;
- a first tab positioned on said outer metalized portion;
- and
- a second tab spaced from said outer metalized portion by a gap with said wireless communication chip positioned between said first tab and said second tab across the gap;
- wherein said first tab and said second tab are constructed out of a conductive material;
- and
- wherein said gap forms a slot antenna configured to operate at a first frequency and said first and second tabs form a dipole antenna configured to operate at a second frequency.
A method of communicating information related to a disc, the method comprising:
- positioning a wireless communication device on said disc by coupling a first tab of said wireless communication device to an outer metalized portion of said disc;
- positioning a second tab on an inner portion of said disc and spaced by a gap from the outer metalized portion of said disc, wherein said first and second tabs are constructed out of a conductive material and form a dipole antenna;
- and
- positioning a wireless communication chip between said first and second tabs such that the gap between said outer metalized portion and said second tab acts as a slot antenna that operates at a first frequency, whereas said dipole antenna is configured to operate at a second frequency.
A wireless communication device comprising:
- a wireless communication chip;
- a first tab electrically connected to said wireless communication chip, wherein said first tab is configured to be coupled to an outer metalized portion of a disc;
- and
- a second tab electrically connected to said wireless communication chip, wherein said second tab is configured to be positioned on an inner portion of said disc;
- wherein the second tab is further configured to be spaced by a gap from said outer metalized portion to form a slot antenna therebetween that operates at a first frequency;
- and
- wherein said first and second tabs form a dipole antenna configured to operate at a second frequency.
A method of communicating information related to a disc, the method comprising:
- positioning a wireless communication device on said disc by coupling a first tab of said wireless communication device to an outer metalized portion of said disc;
- positioning a second tab of said wireless communication device on an inner portion of said disc, wherein said second tab is spaced by a gap from said outer metalized portion of said disc;
- and
- extending a stub from said second tab across said gap.
A method of communicating information related to a disc, the method comprising:
- positioning a wireless communication device on said disc by coupling a first tab of said wireless communication device to an outer metalized portion of said disc;
- positioning a second tab on an inner portion of said disc, wherein said second tab is spaced by a gap from said outer metalized portion of said disc;
- and
- positioning a wireless communication chip between said first and second tabs such that said gap between said outer metalized portion and said second tab acts as a slot antenna.
