Patent 8240562 was granted and assigned to Sony on August, 2012 by the United States Patent and Trademark Office.
A communication apparatus has a first communication section which makes contactless communication by means of magnetic field coupling and a second communication section which makes contactless communication by means of electric field coupling, and the second communication section generates an electric field which oscillates to a direction approximately parallel with an oscillation direction of a magnetic field on a position where the magnetic field crosses the second communication section.
