Abstract
Provided is a non-contact communication apparatus which uses a conventional IC chip without any change, while eliminating the need to transmit power to the IC chip and allowing an increase in communication range. A non-contact communication apparatus connectable to an IC chip includes an antenna section, a first detection section that retrieves a first detection signal from a signal received by the antenna section, an amplitude modulating section that amplitude-modulates a clock signal using the first detection signal retrieved by the first detection section and that inputs the amplitude-modulated signal to the IC chip, a second detection section that retrieves a second detection signal from an output signal from the IC chip, a load modulating section that load-modulates a carrier retrieved from the antenna section using the second detection signal retrieved by the second detection section and that inputs the load-modulated carrier to the antenna section, and a power supply section.
