Abstract
An antenna device includes a ground and a folded antenna element. The ground has a side which has a length Gx smaller than or equal to λ/2 when a signal wavelength is defined as A. The folded antenna element is connected to the side of the ground at a connection point and has a folded element portion folded in a folding direction. Gx1 is defined as a length of a portion of the side between the connection point and an end of the side away from the folded element portion in a direction opposite to the folding direction. The length Gx1 satisfies inequalities: 0≤Gx1<Gx/2.
