Abstract
Provided is a contactless communication system in which each device performing communication in the system includes a dipole antenna having a length which is less than half of wavelength of a clock frequency of digital baseband signals which are communicated. The dipole antennas are disposed in opposing positions to one another. The contactless communication system performs short distance contactless communication of the digital baseband signals using a frequency band which does not include a resonant frequency of the dipole antennas.
