Measurement of Backscattering From RFID Tags
Overview The goal of this paper was to demonstrate how to measure the backscattered signal and calculate the radar cross-section for RFID tags. One presented a theoretical formula for RFID tag RCS and described an experimental method of measuring tag RCS using a network analyzer connected to an antenna in an anechoic chamber with the tag inside. Measurements were performed using RFID tag operating in UHF band. The measurement method was validated by numerical modeling of the RFID tag antenna and calculating its theoretical RCS which agreed well with experimental results.
