Abstract
- RFID systems will soon become ubiquitous. This paper provides insight into one way of viewing the operation of high-frequency RFID systems that use passive tags. The relationship between the impedance of the tag circuit and the fields scattered by the tag are highlighted using two indepen- dent numerical codes. In addition, analytical expressions and numerical results for the scattered electric field are provided for a dipole with an assumed sinusoidal current distribution. Such results provide EMC engineers with an approximate method of determining the fields scattered from passive, high-frequency RFID tags.
