Low Frequency RFID Tag Characterization
Application Notes
The resonance frequency of a radio frequency identification (RFID) tag is a key factor that determines the effective radio communication distance between the tag and the reader. Measuring the resonance frequency of an RFID tag is easy using the Keysight Technologies, Inc. N9321/22C basic spectrum analyzer (BSA).
About RFID Tags
Radio frequency ID (RFID) systems rely on RFID tags, which are small transponders (a combined radio receiver and transmitter) that transmit identity information over a short distance when asked. Generally, an RFID tag contains two parts. One is an integrated circuit for storing and processing information, and modulating and de-modulating an RF signal.
