Abstract:
A high-frequency electric field coupler is provided for use in a contactless communication system propagating high frequency signals in a wide band utilizing electric field coupling. The coupler includes a coupling electrode and a resonance unit operating to increase the amplitude of an electrical charge accumulated at the coupling electrode at a predetermined resonance frequency. The coupling electrode is a linear conductor in the form of a coil.
