ANTENNA DEVICE AND COMMUNICATION DEVICE

WIPO Patent Application WO/2012/036221

A1

The present invention provides an antenna device which is capable of achieving both excellent communication characteristics and mechanical strength, and which has a construction that is useful in the miniaturization of coupling electrodes. The antenna device has a construction in which a coupling electrode (18) comprises: a dielectric substrate (11) having an earth (12) formed on one face of the dielectric; and wiring (15) formed on the face of the dielectric substrate (11) that is opposite to the face where the earth (12) is formed. The coupling electrode (18) becomes capable of communication by being electromagnetically coupled to an electrode of another antenna device that is positioned facing the antenna device. The coupling electrode (18) has a plurality of folding sections and comprises the wiring (15), said wiring (15) having a length that is substantially half the communication wavelength. A connection terminal (19) constituting a signal input/output terminal is formed at one end section of the wiring (15), and the other end section thereof is electrically connected to the earth (12).
