Radio Frequency (RF) surface wave transmission lines support low-loss on-body propagation, and have recently attracted significant interest for wearables. In this work, the effect of fabric moisture absoption on a surface-wave textile Single Wire Transmission Line (SWTL) is analyzed in the Ultra High-Frequency (UHF) spectrum from 0.5 to 4 GHz. It is shown that moisture can increase the losses (in dB) by four-fold. The42 cm SWTL maintains an insertion loss around 15 dB up to at 2.4 GHz, when the substrate is covered fully in water. The measured response is compared to a printed textile micro strip line; the surface-wave SWTL exhibits a more linear response to the moisture content indicating its suitability for RF moisture sensing applications.

Abstract

Radio Frequency (RF) surface wave transmission lines support low-loss on-body propagation, and have recently attracted significant interest for wearables. In this work, the effect of fabric moisture absoption on a surface-wave textile Single Wire Transmission Line (SWTL) is analyzed in the Ultra High-Frequency (UHF) spectrum from 0.5 to 4 GHz. It is shown that moisture can increase the losses (in dB) by four-fold. The42 cm SWTL maintains an insertion loss around 15 dB up to at 2.4 GHz, when the substrate is covered fully in water. The measured response is compared to a printed textile micro strip line; the surface-wave SWTL exhibits a more linear response to the moisture content indicating its suitability for RF moisture sensing applications.
