An antenna comprises a base (3), a ground conductor (5), a first antenna element (7) and a second antenna element (9). The base (3) is a thin plate made of a dielectric material. The ground conductor (5) is a strip-shaped thin-film conductor disposed on the base (3). The first antenna element (7) is an L-shaped thin-film conductor disposed on the base (3). One end of the first antenna element (7) is connected to one end (5A) of the ground conductor (5). The second antenna element (9) is a strip-shaped thin-film conductor and so arranged on the base (3) as to be insulated from the ground conductor (5) and the first antenna element (7). |
