Wideband Harmonic Tag Modulating Sensor-Information by Pass-Band Width
Get PDFThis paper proposes a passive harmonic tag that modulates sensor information on the pass-band width in the 2.5 GHz / 5.0 GHz bands. It incorporates an energy harvester that uses the DC output from the frequency doubler. The system employs two independent antennas for downlink and uplink communication and utilizes an attenuator to achieve wideband impedance matching. In this paper, the sensor is modeled as a small DC cell with a potentiometer for basic considerations. The experimental results show that the sensor voltage in the remote tag is successfully extracted at a 6-meters spacing between the base-station antennas. Additionally, it is demonstrated that it takes 12 minutes to charge the capacitor in the harvester to over 1V.2024 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM)
