Abstract
An antenna device is provided and includes a circuit board, a first linear antenna, and a second linear antenna. The circuit board includes a grounding pattern and a feeding point insulated from the grounding pattern. The first linear antenna is connected to the grounding pattern and includes a first inductive element positioned between distal ends of the first linear antenna. The second linear antenna is connected to the feeding point and capacitively coupled to one of the distal ends of the first linear antenna. The second linear antenna includes a second inductive element positioned proximate a middle section of the second linear antenna.
