ANTENNA DEVICE AND MOBILE WIRELESS APPARATUS EMPLOYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an antenna device the isolation characteristic of which can be enhanced by reducing the coupling among antenna elements and to provide a mobile wireless apparatus employing the same. SOLUTION: The antenna device includes: a bottom board 10; a first antenna element 11 corresponding to a first frequency band; a second antenna element 12 corresponding to a second frequency band close to or overlapped on the first frequency band; a first feeding part 13 for connecting the bottom board 10 to the first antenna element 11; and a second feeding part 14 for connecting the bottom board 10 to the second antenna element 12, wherein the first antenna element 11 and the second antenna element 12 are arranged in parallel with a long side of the bottom board 10.
