<p><P>PROBLEM TO BE SOLVED: To provide an antenna device having a structure advantageous for downsizing a coupling electrode while enabling both excellent communication property and mechanical strength to be achieved. <P>SOLUTION: The antenna device comprises a dielectric substrate 11 in which a ground 2 is formed on one face of a dielectric, and a coupling electrode 18 including wiring 15 formed on a face of the dielectric substrate 11 on a face opposite to the face on which the ground 2 is formed and electromagnetically coupled to an electrode of another antenna device disposed at a position facing the own antenna device to be communicable with the other antenna device. The coupling electrode 18 includes a plurality of folded parts and the wiring 15 having a length approximately half of a communication wavelength. A connection terminal 19, the terminal for signal input/output, is formed on one end part of the wiring 15 and another end part is electrically connected to the ground 2. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
