A miniaturized wireless and passive antenna sensor with meandering structure for integrated multi-directional strain and temperature sensing.

( 8 ), the relative permittivity of the patch antenna substrate exhibits an increasing trend as the ambient temperature rises.

As can be observed from the fitting curves in these three subfigures, with the increase of both temperature and strain in a specific direction, the resonant frequency at the corresponding resonant point in that direction shows a decreasing trend, which aligns with theoretical expectations; simultaneously, the strain sensitivity in that direction also gradually increases as temperature rises.
