RFID and distance measurement

Hello Guys,

I have a new project that I want use RFID to verify ID of item and I need measurement distance from reader to TAG. The maximum distance between the reader to TAG is about 7 cm and I want know distance between reader to TAG with accuracy about 1 cm.

Is it possible?

125KHz RFID reader anntena coil - Forum for Electronics

i need some help pls... i currently modified a 125KHz RFID reader anntena coil, the actual read range for 125KHz RFID reader is about 4cm. I plan to remove the original anntena coil and replace with another anntena coil to improve the reading range. so, what type of material i needed to build the antenna coil? for example copper? is that correct? how many turn for the anntena coil? how many...

13.56MHz PA for RFID reader reference design.

I found an application note from MicroChip about a 13.56MHz RFID reader reference design. I attached the schematic here. I have some questions:...

For the power amplifier, how to design the matching network? how to decide the component value?

In this PA design, the value of RF chock L1 is not large (0.47 uH), actually it has the same value as L2. Why? Also, C9, C10 and C31 are connected in...

antennas for 8.2 MHz Tag detection - edaboard.com

Re: antennas for 8.2 MHz Tag detection

Your best bet would probably be a multi turn loop antenna tuned to resonance.

The loop could be made quite small, or surround an entire enclosed area, depending on your requirements.

Cheers, Tony.

Re: antennas for 8.2 MHz Tag detection

Thank you Tony,

Most of practical systems have rather large antennas. And area of detection - distance between the antennas...

RFID simulation HFSS

Hello,

Indeed, i am working on UHF tag antenna and i simulat them using HFSS simulator. For excitation, i put a 50 Ohm lumped port ( idont know if is it good or false) but what i have difficulty understanding how can i extract the internal impedance of the antenna. In another, mean, did the fact to have a port of 50 Ohm can disturb the internal impedance of the antenna and...
