WIRELESS COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2004/093443

Kind Code:

A1

Abstract:

In a liquid crystal television device (10) as a wireless communication device, speaker-receiving portions (12a, 12b) are formed integrally with a body portion (11) where components such as a liquid crystal panel portion (13) etc. are received. The body portion (11) is electromagnetically shielded but not so are the speaker-receiving portions (12a, 12b). Antennas (15a, 15b) are arranged in the speaker-receiving portions (12a, 12b) together with speakers (14a, 14b) such that the installation directions of the antennas are shifted 90 degrees to each other. The wireless communication device has an antenna structure capable of improving transmission-reception sensitivity in all directions.
