Abstract
In accordance with some embodiments, a wideband non-folded on-metal UHF RFID tag is disclosed. The wideband non-folded on-metal UHF RFID tag 100 may include a substrate and an antenna. The antenna may comprise a first dipole antenna with a first cut-out groove, a second dipole antenna with a second cut-out groove, a first loop antenna and a second loop antenna disposed within a central region of the antenna. The wideband non-folded on-metal UHF RFID tag 100 may include an RFID chip embedded to a center of the central region of the antenna, and a dielectric substrate adhered to an under surface of the antenna and the RFID chip.
Claims25
A wideband non-folded on-metal UHF RFID tag comprising:
- an antenna comprising:
- a first dipole antenna with a first cut-out groove;
- a second dipole antenna with a second cut-out groove;
- and
- a first loop antenna and a second loop antenna disposed within a central region of the antenna;
- and
- an RFID chip embedded at a center of the central region of the antenna.
A method of operation of a wideband non-folded on-metal UHF RFID tag, the method comprising:
- receiving an incoming RF signal via an antenna of the wideband non-folded on-metal UHF RFID tag;
- transferring the received incoming signal to an RFID chip of the wideband non-folded on-metal UHF RFID tag through the antenna;
- responding to the received incoming signal to trigger the RFID chip to resonate at at least one of two resonant frequencies matching one at a time;
- transmitting an output signal from the RFID chip back to the antenna;
- and
- radiating the output signal via the antenna.
A method for manufacturing a wideband non-folded on-metal tag, the method comprising:
- cutting a metal sheet to form an antenna;
- constructing a first dipole antenna with a first cut-out groove and a second dipole antenna with a second cut-out groove from the antenna;
- and
- forming a first loop antenna and a second loop antenna within a central region of the antenna.
