Abstract
A thin-film coil assembly includes a flexible substrate, an oscillation starting antenna, a resonant antenna, a first protective layer and a second protective layer. The flexible substrate has a first surface and a second surface opposed to the first surface. The oscillation starting antenna is disposed on the first surface of the flexible substrate. The resonant antenna is disposed on the second surface of the flexible substrate. Moreover, at least one capacitor is connected between a first end and a second end of the resonant antenna. An electromagnetic wave with a specified resonant frequency is emitted or received by the thin-film coil assembly in response to a resonant coupling effect of the resonant antenna and the oscillation starting antenna. The first protective layer covers the oscillation starting antenna. The second protective layer covers the resonant antenna.
