Fig. 2

a Optical microscope image of a fabricated smart ME antenna; b S11 of the thickness mode of the smart ME antenna showing a resonance frequency at 2.51 GHz; c S11 of the width mode of the smart ME antenna showing a resonance frequency at 63.6 MHz. The insets in (b) and (c) show the equivalent MBVD circuit model of ME antenna in each mode; d The left-axis shows the measured PTE versus distance between ME antenna and Tx coil, and the right axis shows the simulated magnetic flux density along the x-axis (Bx) generated by the Tx coil versus distance from Tx coil.
