In this paper, we show that negative differential resistance devices, such as tunnel diodes, exhibit 27 dB more gain and 10 dB lower power consumption than state-of-the-art . In this letter, we design and implement a long-range FM band backscatter tag amplifier with the tunnel diode. This tag has not only low power consumption but also a longer .In this paper, we present a 5.8 GHz RFID tag equipped with a high gain, low power reflection amplifier based on a tunnel diode. Experimental results show that the realized prototype achieves gains above 40 dB and requires only 29 μW of biasing power.
In this paper, we show that negative differential resistance devices, such as tunnel diodes, exhibit 27 dB more gain and 10 dB lower power consumption than state-of-the-art reflection amplifiers.This reflection amplifier consumes 0.2 mW DC power at bias voltage of 200 mV, making it an ideal candidate to amplify backscattered electromagnetic field in RFID transceivers. The gain of the proposed reflection amplifier is 17 dB for the incident power of -30 dBm. Moreover, an Effective Isotropic Radiated Power (EIRP) of only 10.5 dBm and a biasing power for the tunneling tag of only 21.3 μW at 80 mV promise a low-power, long-range sub-meter scale positioning technique with a projected maximum range over 1 km.
We reduce the long-range PV-RFID idea to practice by creating functional prototypes of: 1) a wireless building environment sensor to monitor temperature and 2) an embedded tracker to find lost golf balls. The read range of PV-RFID is enhanced eight times compared to conventional passive devices.
This paper presents a 5.8-GHz RFID tag that, by exploiting the quantum tunneling effect, significantly increases the range of backscatter radio links. We present an electronically simple Tunneling RFID Tag characterized by return gains as high as 35 dB with link sensitivity as low as -81 dBm.In this letter, we design and implement a long-range FM band backscatter tag amplifier with the tunnel diode. This tag has not only low power consumption but also a longer backscatter distance compared with the traditional FM backscatter tag.To help increase the read-range of semi-passive RFID tags, this research proposes a preliminary design for a retrodirective, tunneling RFID tag architecture that loads a rat-race coupler with reflection amplifiers made with low-power tunnel diodes. The work presented here demonstrates a low-power two-way repeater architecture capable of increasing the read range and extending the coverage of tags to non-line-of-sight (NLOS) scenarios. This is achieved through the use of a two-way frequency divided tunnel diode-based reflection amplifier optimized for use in backscattering channels.
The authors want to give an overview about the research progresses done in the latest years to enhance ranges of microwave backscattering communications with RFIDs exploiting the tunneling effect of tunnel diodes.
