<p>An antenna device (1) is provided that can easily adjust the resonant frequency and bandwidth of a first-order mode and that has a wider bandwidth characteristic of a bandwidth. In the antenna device (1), a first linear antenna element (3) connected to a grounding pattern (2) and a second linear antenna element (5) connected to a feeding point (4) are capacitively coupled by a capacitive coupling portion (7) at distal ends thereof. Inductive elements (L1, L2) are interposed in middle parts of the first linear antenna element (3) and the second linear antenna element (5), respectively.</p> |
