<P>PROBLEM TO BE SOLVED: To provide an antenna which can be installed within a narrow space and can easily acquire a plurality of accurate resonant frequencies belonging to isolated frequency bands, respectively. <P>SOLUTION: A double resonant antenna 1 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 4 and the first antenna element 7. <P>COPYRIGHT: (C)2007,JPO&INPIT |
