Toward the Optimal Antenna-Based Wireless Sensing Strategy: An Ice Sensing Case Study
Remote ice detection has emerged as an application of Radio Frequency (RF) sensors. While antenna-based “RFID” sensing can detect various measurands, antenna-based sensors are not currently designed based on a systematic methodology, and in most cases may have a low sensitivity requiring specialist
hardware or broadband interrogation signals, incompatible with
spectrum regulations. Here, we develop a systematic methodology
for designing an antenna-based sensor, applicable to measurands
inducing a dielectric change in the near-field of the antenna.
The proposed methodology is applied to designing printable
antennas as highly-sensitive sensors for detecting and measuring
the thickness of ice, demonstrating best-in-class sensory response
compared to more complex antenna designs. Antenna design is investigated systematically for wireless interrogation in the 2.4 GHz band, where it is found that a loop antenna outperforms a dipole owing to its more distributed capacitance. The antenna’s realized gain was identified as the optimum parameter-under-test, with “positive” sensing proposed as a method of improving linearity and immunity to interference. The developed loop antenna sensor exhibits resilience to interference and applicability to different real-world deployment environments, demonstrated through over 80% average ice thickness measurement accuracy and at least 5 dB real-time sensitivity to ice deposition.

Abstract

Remote ice detection has emerged as an application of Radio Frequency (RF) sensors. While antenna-based “RFID” sensing can detect various measurands, antenna-based sensors are not currently designed based on a systematic methodology, and in most cases may have a low sensitivity requiring specialist
hardware or broadband interrogation signals, incompatible with
spectrum regulations. Here, we develop a systematic methodology
for designing an antenna-based sensor, applicable to measurands
inducing a dielectric change in the near-field of the antenna.
The proposed methodology is applied to designing printable
antennas as highly-sensitive sensors for detecting and measuring
the thickness of ice, demonstrating best-in-class sensory response
compared to more complex antenna designs. Antenna design is investigated systematically for wireless interrogation in the 2.4 GHz band, where it is found that a loop antenna outperforms a dipole owing to its more distributed capacitance. The antenna’s realized gain was identified as the optimum parameter-under-test, with “positive” sensing proposed as a method of improving linearity and immunity to interference. The developed loop antenna sensor exhibits resilience to interference and applicability to different real-world deployment environments, demonstrated through over 80% average ice thickness measurement accuracy and at least 5 dB real-time sensitivity to ice deposition.
