ABSTRACT:
An antenna comprises a base member (3), a ground conductor (5), a first antenna element (7) and a second antenna element (9). The base member (3) is formed in a thin plate shape and made of dielectric material. The ground conductor (5) is formed of a thin-film shaped and rectangular conductor and disposed on the base member (3). The first antenna element (7) is formed of a thin-film shaped and L-shaped conductor, is disposed on the base member (3) and has one end connected to one end (5A) of the ground conductor (5). The second antenna element (9) is formed of a thin-film shaped and rectangular conductor and is disposed on the base member (3) to be isolated from the ground conductor (5) and the first antenna element (7).
