Hi folks,
I am planning on performing tests on an RFID passive tag antenna (spiral coil), without a Tag IC connected. I will have the tag at various distances from an RFID reader antenna.
How can I reliably measure the DC voltage induced across the tag coil? I've found a possible setup from Texas Instruments(See Link Below)
See Page 10
**broken link removed**
Is there anyway to measure the power/voltage induced on the tag wirelessly?
I assume if any probes are connected to the coil then the results won't be accurate.
Any advice is much appreciated
Kind Regards
