Document Type and Number:
WIPO Patent Application WO/2011/122162
Kind Code:
A1
Abstract:
Disclosed is a composite antenna, which has improved gain of a second antenna by having two antennas that resonate in different frequency bands relate to each other, and which can be used as a single antenna even in a first frequency band. Also disclosed is a composite wireless communication device.
The composite antenna is provided with a first antenna (10) that resonates in the first frequency band, and the second antenna (20) that resonates in a second frequency band higher than the first frequency band. The first antenna (10) and the second antenna (20) are respectively configured of coil-like electrodes (11a, 11b) and coil-like electrodes (21a, 21b), which are formed on the front surface and the rear surface of an insulating base material (2) by facing each other. Furthermore, the first antenna (10) and the second antenna (20) are electrically connected to each other on the front surface of the base material (2) by means of a connecting section (15).
