Title:
NEAR FIELD COMMUNICATION APPARATUS, AND SEMICONDUCTOR INTEGRATED CIRCUIT FOR NEAR FIELD COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2011/048728
Kind Code:
A1
Abstract:
Disclosed is a near field communication apparatus which includes: a first resonant circuit including a first antenna; a reader/writer functional section, which generates alternating current signals of predetermined output by means of predetermined start-up signals, and supplies the alternating current signals to the first resonant circuit; and a second antenna. Furthermore, the near field communication apparatus is provided with: a second resonant circuit which is synchronized with the first resonant circuit with electromagnetic induction between the first antenna and the second antenna; a non-contact IC card functional section which generates predetermined electric information by means of the synchronization of the second resonant circuit; and a resonant circuit adjusting section, which adjusts the resonance characteristics of the first resonant circuit or those of the second resonant circuit, based on predetermined electric information generated in the non-contact IC card functional section.
