Abstract

A novel matching way between antenna of a 2.45GHz active RFID tag and power amplifier (PA) is presented in this paper. Dipole antenna is not only used as a transmitting antenna of the RFID tags, but also as a differential amplifier resonant inductor. The total PA chip size is reduced greatly to only 240μm70μm in a 0.18μm CMOS process due to saving two on-chip integrated inductors. The total tag size is reduced greatly to only 42mm18mm owing to meandered dipole antenna.
