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.
Claims32
A disc having a metal region for the storage of data thereon coupled to a wireless communication device,
- the disc comprises an outer metalized portion and the outer metalized portion includes the metal region;
- and
- 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;
- 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 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 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 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 metalized outer portion of a disc and electrically connected to said wireless communication chip;
- a second tab adapted to position on an inner portion of the disc and electrically connected to said wireless communication chip;
- and
- said second tab adapted to be spaced from the outer metalized portion so as to form a slot antenna therebetween.
