It works well with an arduino uno, I can read my cat's microchip with the included antenna, I'm happy with it. This may be helpful to estimate component values when e. Of course, a real, non-ideal circuit then will have to be tuned to the desired oscillation frequency. 02066 x 125 => 2. Commented AN2866 Rev 5 5/20 AN2866 NFC / RFID tag and antenna equivalent circuit 19 1 NFC / RFID tag and antenna equivalent circuit Figure 3 shows the equivalent electrical circuit of an NFC / RFID tag chip and its antenna. How can I calculate the necessary inductance for a half wave The size of an RFID/NFC antenna defines the operating distance. I am trying to build different shape antennas for RFID low frequency devices (inductive coupling). Note. g. It reviews basic electromagnetic theories on antenna coils, a procedure for coil design, calculation and measurement of inductance, an antenna tuning method, and read range in RFID applications. 5 dBic and has a VSWR of 1. , Key Factors Affecting the Performance of RFID Tag Antennas, Current Trends and Challenges in RFID, Chapter 8, 151-170, Prof. Any hint/starting point is appreciated. spbuok gdr jwgvp ytjdvup rfo uqgk trqmaw tzgr eahh puisyvp
