Abstract
A first antenna element includes a first end connected to a feedpoint, a second end connected to a connection point on a ground conductor, and a fold disposed between the first and the second ends. A part of a segment between the first end and the fold of the first antenna element is disposed along the ground conductor. A second antenna element branches off the first antenna element. The second antenna element is disposed between the part of the first antenna element disposed along the ground conductor and the ground conductor. The segment between the first end and the fold of the first antenna element resonates at a first frequency. The second antenna element and a segment between the first end and a branch point of the first antenna element resonate at a second frequency that is higher than the first frequency.
