Dual frequency RFID circuit

Dual frequency RFID circuit

A radio frequency identification (RFID) transponder (FIGS. 4 and 5 A) is disclosed. The transponder includes first (RF) and second (GND) terminals. A first resonant circuit ( 500, 504, 508 ) is connected between the first and second terminals. A second resonant circuit ( 502, 504, 508 ) has a second...

Zusammenfassung:A radio frequency identification (RFID) transponder (FIGS. 4 and 5 A) is disclosed. The transponder includes first (RF) and second (GND) terminals. A first resonant circuit ( 500, 504, 508 ) is connected between the first and second terminals. A second resonant circuit ( 502, 504, 508 ) has a second resonant frequency different from the first resonant frequency and is connected between the first and second terminals.
