Title:
WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/121893
Kind Code:
A1
Abstract:
The disclosed wireless communication device (100) is provided with: an antenna element (40) that faces at least part of a conductive plate that a conductive surface (second casing) has or a conductive layer that a circuit board (30) has; and a plurality of conductive elements (36) that are positioned between the antenna element (40) and said conductive surface and that are repeatedly arrayed in a manner so as to intersect in the direction orthogonal to said conductive surface. The wireless communication device is, for example, a slide-opening/closing cellular telephone, and is provided with a first casing (10), a second casing (20), and a flexible circuit board (30). By means of the first casing (10) and the second casing (20) sliding against each other, the wireless communication device (100) switches between the belowmentioned first state and second state. In the first state, the circuit board (30) is folded over, and in the second state, the circuit board (30) is extended more than in the first state.
