Abstract
An RFID device utilizing a single antenna for multiple resonant frequency ranges. RFID device that can include an RFID circuit, and a single antenna coupled to the RFID circuit. The antenna can be configured to operate within multiple frequency ranges for communicating with at least one RFID interrogator according to respective protocols associated with each respective frequency range.
Claims21
A radio frequency identification (RFID) system comprising:
- an RFID interrogator, having an interrogator antenna, configured to operate within multiple frequency ranges;
- and
- an RFID device having
- a device antenna, the device antenna having a single antenna structure resonant on at least the multiple frequency ranges, and
- an RFID circuit coupled to the device antenna and configured to use the single antenna structure to communicate with the RFID interrogator according to different protocols simultaneously over the multiple frequency ranges, each protocol of the different protocols using a respective frequency range of the multiple frequency ranges.
