<p>Provided is an antenna device which is capable of flexibly adjusting multiple resonance frequencies. The antenna device is provided with a substrate main body (2), a ground pattern (GP), a first element (3), a second element (4) and a third element (5). The ground pattern extends in one direction while being connectable to a ground, the first element extends with the first passive element (P1) and the first antenna element (AT1) provided thereon, the second element extends with the tip end thereof connected to a connecting part (C), the third element extends with the second passive element (P2) connected thereto, the first element extends with a gap provided between the first element and each of the second element, the third element, and the ground pattern so as to be able to generate a stray capacitance therebetween, and the ground pattern extends with the tip end thereof provided within a range from a position facing the connecting part (C) to a position facing the first passive element.</p> |
