Summary

We demonstrate a practical concept to extend the performance at the air interface of RFID proximity readers using integrated reader chips. Our solution consists of an external, discrete circuit and we consider the transmit path as well as the receive path. We discuss important aspects for design and evaluate the quality improvement for a specific reader in some relevant characterization measurements.

Zusammenfassung

Die Autoren zeigen ein praktisches Konzept zur Verbesserung der Leistungsfähigkeit von RFID Proximity Readern an der Luftschnittstelle. Die Lösung besteht aus einer diskreten Schaltung zur Erweiterung integrierter Reader Chips, mit der die Ausgangsleistung im Sendezweig gesteigert und die Empfindlichkeit im Empfangszweig erhöht wird. Weiters werden wesentliche Aspekte für das Design betrachtet und der Qualitätsgewinn anhand relevanter Charakterisierungs-Messungen für einen Reader deutlich gemacht.
