Title:
ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2014155100
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna device having an operating frequency band broadened without changing the thickness of the device.SOLUTION: The antenna device has a structure in which an anisotropic conductive adhesive 7 is disposed on a surface of a dielectric substrate 1a on which a matching circuit 2 is formed and the surface of the dielectric substrate 1a and a back surface of a dielectric substrate 1b are placed to face each other such that an opposite end of the matching circuit 2 opposes a stripe conductor pattern 5, with them provided between the surface of the dielectric substrate 1a and the back surface. The dielectric substrates 1a and 1b are bonded to each other with the anisotropic conductive adhesive 7 so that the opposite end of the matching circuit 2 and the strip conductor pattern 5 are electrically connected to each other, thus enabling an operating frequency band broadened without changing the thickness of the antenna device.
