On the measurement of the delta Radar Cross Section (ΔRCS) for UHF tags

Abstract : This paper presents a methodology for the practical measurement of the variation of the radar cross section for the RFID UHF tags. This is a very critical parameter, and will govern the tag performance. It also influences both the reading distance as well as the sensitivity of UHF tag. The paper includes the analysis procedure and the experimental setup. The later is based on standard equipments such as an anechoic environment, a vector signal generator and a vector signal analyzer. The application of the proposed method is illustrated on some samples of EPC GEN2 UHF tag. The delta RCS is obtained as a function of the reader power.
