PROBLEM TO BE SOLVED: To provide a surface mount antenna 1 for multiband. SOLUTION: A powered element 3 and a non-powered element 4 are mutually formed at an interval on the surface of a dielectric substrate 2. The powered element 3 is constituted by extending a power feed radiating electrode 7 from a power feed terminal 5, and the nonpowered element 4 is formed as a branched element by branching and extending a first radiating electrode 8 and a second radiating electrode 9 on a non-power side from the side of a ground terminal 6. Since one surface mount antenna 1 is provided with three radiating electrodes 7, 8 and 9, the antenna 1 can be easily used in multiband. Further, since the respective resonance waves of the radiating electrodes 7, 8 and 9 can be independently controlled, a frequency band can be widened by making only a frequency band, which is selected out of requested plural frequency bands, into dual bump resonance. |
