Matching-Circuit Calculation for the CRX14 Coupler
In the basic RFID system (as shown in Figure 1):
1. The Reader generates an electromagnetic field. This field is rectified to generate the
supply voltage inside the Tag.
2. The Reader transmits information to the Tag by modulating the carrier wave.
3. The Tag back-scatters the carrier wave, by modifying its own impedance thereby
perturbing the field, in order to transmit back information to the Reader.
