Dual band built-in antenna device and mobile wireless terminal equipped therewith
First Claim
1. A dual band built-in antenna device operable in a first frequency band and a second frequency band comprising:
- a ground plane comprising a ground member;
a first inverted-L line antenna element for said first frequency band; and
a second inverted-L line antenna element for said second frequency band;
wherein said first and second inverted-L line antenna elements are so constructed that the elements are extended to respective directions that are further separated from each other as the antenna elements extend further from a starting position set in proximity to a power feed point within a plane parallel to said ground plane.

Abstract
A dual band built-in antenna device operable in a first frequency band and a second frequency band is provided. The antenna device comprises a ground plane comprising a ground member, a first inverted-L line antenna element for the first frequency band, and a second inverted-L line antenna element for the second frequency band. The first and second inverted-L line antenna elements are so constructed that the elements are extended to respective directions that are further separated from each other as the antenna elements extend further from a starting position set in proximity to a power feed point within a plane parallel to the ground plane.
