Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/111975
Kind Code:
A1
Abstract:
Provided is an antenna device capable of flexible adjustment of each multi-resonant resonant frequency, and which can be miniaturized and made thin. The present invention is provided with an insulating substrate main body (2), ground surfaces (GND) which are each patterned with metal foil on the substrate main unit, a first element (3), and a second element (4). For the first element, a feeding point (FP) is provided on, and extends, a proximal end disposed on the ground surface side. Partway in the first element, an antenna element (AT) of a dielectric antenna is connected, and at a distal end, a first auxiliary antenna portion (6) is connected. The second element is connected to the proximal end side of the first element and extends the same, wherein a passive element (P2) is connected partway, and at a distal end, a second auxiliary antenna portion (7) is connected. The first auxiliary antenna portion and the second auxiliary antenna portion are formed with a flexible thin film conductor, are folded back, and above the substrate main body, extend from the substrate main body so as to be spaced apart from the same.
