Title:
ANTENNA DEVICE AND COMMUNICATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2015/016353
Kind Code:
A1
Abstract:
An antenna device comprising an insulating substrate section (A), an antenna pattern (15) formed on said insulating substrate section (A), another insulating substrate section (B), and wiring conductors (31, 32) formed on top of said insulating substrate section (B). The antenna pattern (15) is spiral-shaped and has a first end (15a) and a second end (15b). In a plan view, an electrical-isolation layer (20) for electrically isolating the wiring conductors (31, 32) from the pattern (15) is interposed in the region between the first end (15a) and the second end (15b) of the pattern (15). The wiring conductors (31, 32) have a plurality of electrode sections (31a, 32a) that are electrically and mechanically connected to the first end (15a) and the second end (15b) of the pattern (15), respectively, via a conductive material. The electrical-isolation layer (20) has cutouts (20a, 20c) that expose one or both ends (15a and/or 15b) of the pattern (15) to the wiring-conductor (31, 32) side before the wiring conductors (31, 32) are connected to the pattern (15). The wiring conductors (31, 32) and the pattern (15) are connected via the abovementioned conductive material in the areas where the cutouts (20a, 20c) in the electrical-isolation layer (20) are formed. One insulating substrate section (B) is more flexible than the other insulating substrate section (A).
