A sensor and system provide for radio frequency identification (RFID)-enabled information collection. The sensor includes a ring-shaped element and an antenna. The ring-shaped element includes a conductive ring and an RFID integrated circuit. The antenna is spaced apart from the ring-shaped element and defines an electrically-conductive path commensurate in size and shape to at least a portion of the conductive ring. The system may include an interrogator for energizing the ring-shaped element and receiving a data transmission from the RFID integrated circuit that has been energized for further processing by a processor.

1. A system for radio frequency identification (RFID)-enabled information collection, comprising: a plurality of ring-shaped elements arrayed linearly in a spaced apart fashion in a plane, each of said ring-shaped elements including an electrically-conductive ring and an RFID integrated circuit electrically coupled to said electrically-conductive ring;a movable support;an antenna coupled to said movable support for movement therewith, said antenna defining an electrically-conductive path commensurate in size and shape to at least a portion of said electrically-conductive ring;an interrogator for transmitting a signal to said antenna wherein said electric current is generated along said electrically-conductive path and electromagnetic energy emanates from said antenna, wherein at least one of said ring-shaped elements and said RFID integrated circuit associated therewith is energized by said electromagnetic energy, and wherein each said RFID integrated circuit so-energized generates a data transmission for receipt by said interrogator; anda processor coupled to said interrogator for deriving information related to position of said movable support using said data transmission. 2. The system of claim 1, wherein said electrically-conductive path is parallel to said plane. 3. The system of claim 1, wherein each of said ring-shaped elements is rectangular. 4. The system of claim 1, wherein said data transmission includes a unique identity for each said RFID integrated circuit. 5. The system of claim 1, wherein said antenna is selected from the group consisting of a microstrip patch antenna, a slot antenna, a dipole antenna, and a planar inverted-F antenna. 6. The system of claim 1, wherein said movable support comprises a portion of a product dispenser adapted to store products, and wherein said movable support experiences movement whenever one of the products is removed from said product dispenser. 7. The system of claim 6, further comprising an elastic element coupled to said movable support for causing said movement whenever one of the products is removed from said product dispenser. 8. The system of claim 6, wherein such movable support is configured such that gravity causes movement of said movable support whenever one of the products is removed from said product dispenser. 9. The system of claim 1, further comprising a reference ring-shaped element coupled to at least one of said antenna and said movable support for movement therewith, said reference ring-shaped element maintained in a fixed relationship with respect to said antenna, said reference ring-shaped element including an electrically-conductive reference ring and a reference RFID integrated circuit electrically coupled to said electrically-conductive reference ring, said reference ring element being positioned to be energized by said electromagnetic energy emanating from said antenna. 10. The system of claim 1, wherein said data transmission includes magnitude and phase information associated therewith. 11. A system for radio frequency identification (RFID)-enabled information collection, comprising: a plurality of ring-shaped elements arrayed linearly in a spaced apart fashion in a plane, each of said ring-shaped elements defining a series circuit to include an electrically-conductive rectangular ring and an RFID integrated circuit;a movable support;an antenna coupled to said movable support for movement therewith, said antenna defining an electrically-conductive path commensurate in size and shape to at least a portion of said rectangular ring, said electrically-conductive path being parallel to said plane;an interrogator for transmitting a signal to said antenna wherein said electric current is generated along said electrically-conductive path and electromagnetic energy emanates from said antenna, wherein at least one of said ring-shaped elements and said RFID integrated circuit associated therewith is energized by said electromagnetic energy, and wherein each said RFID integrated circuit so-energized generates a data transmission for receipt by said interrogator; anda processor coupled to said interrogator for deriving information related to position of said movable support using said data transmission. 12. The system of claim 11, wherein said data transmission includes a unique identity for each said RFID integrated circuit. 13. The system of claim 11, wherein said antenna is selected from the group consisting of a microstrip patch antenna, a slot antenna, a dipole antenna, and a planar inverted-F antenna. 14. The system of claim 11, wherein said movable support comprises a portion of a product dispenser adapted to store products, and wherein said movable support experiences movement whenever one of the products is removed from said product dispenser. 15. The system of claim 14, further comprising an elastic element coupled to said movable support for causing said movement whenever one of the products is removed from said product dispenser. 16. The system of claim 14, wherein such movable support is configured such that gravity causes movement of said movable support whenever one of the products is removed from said product dispenser. 17. The system of claim 11, further comprising a reference ring-shaped element coupled to at least one of said antenna and said movable support for movement therewith, said reference ring-shaped element maintained in a fixed relationship with respect to said antenna, said reference ring-shaped element including an electrically-conductive reference ring and a reference RFID integrated circuit electrically coupled to said electrically-conductive reference ring, said reference ring element being positioned to be energized by said electromagnetic energy emanating from said antenna. 18. The system of claim 11, wherein said data transmission includes magnitude and phase information associated therewith.
