アンテナ装置及び無線装置
Document Type and Number:
Japanese Patent JP6774555
Kind Code:
B2
Abstract:
The present invention provides an antenna device whose radiation direction is adjustable and which can be manufactured at a lower cost than in the case of a conventional antenna device. An antenna device (1) includes a dielectric substrate (11), a ground conductor (12) provided on a first main surface of the dielectric substrate (11), and an antenna conductor (13) provided on a second main surface of the dielectric substrate (11). The ground conductor (12) is made of a conductor material having a thermal expansion coefficient higher than that of a dielectric material of which the dielectric substrate (11) is made. A heating wire (16) which serves as a heating/cooling mechanism is provided inside the dielectric substrate (11).
