摘要 |
The present invention relates to an electricity feeding structure, comprising: a resonator including an electricity feeding part and a ground part connected to the electricity feeding part; a resonance adding part disposed between the electricity feeding part and the ground part; and a controlling part disposed in at least one of the electricity feeding part, the resonance adding part and the ground part. According to the present invention, since the electricity feeding structure includes the controlling part, it is possible to easily control the resonant frequency band of an antenna device. |
