- Abstract
A small 2.45 GHz radio frequency identification (RFID) tag antenna is presented. The RFID tag antenna is designed as a resonance inductance of the differential power amplifier (PA). The total PA chip area is reduced greatly to only 240 μm x 70 μm due to the fact that a printed circuit board (PCB) dipole antenna substitutes for the two on-chip integrated inductors. The proposed design methodology is verified by comparing the calculations and measurements, which show the tag antenna works at 2.45 GHz. Operating in Class-AB with a 1.8 V supply voltage and 2.45 GHz input signal, the PA shows an output power of 8 dBm at the 1 dB compression point.
