Abstract
An RFID tag antenna system comprises a tag antenna with complex impedance and an integrated circuit (IC) with input impedance. A controlled mismatch between the tag antenna and IC impedances reduces the realized gain of the tag antenna to a desired level. The system calculates a reflection coefficient to reduce antenna gain by a predetermined amount. A program converts the reflection coefficient to realized gain and calculates theoretical read distance based on realized gain and IC sensitivity. The process generates a read distance profile over frequency. This approach enables precise control of RFID tag performance, allowing customization for specific applications while maintaining optimal functionality.
