| 摘要 |
The present invention relates to a resonance frequency variable type antenna which has as low operating frequency as mobile broadcasting service bands of T-DMB and DVB-H and a wide frequency bandwidth and can select and receive various channels using a loop antenna capable of varying a resonance frequency through a variable capacitor. Particularly, the resonance frequency variable antenna can be mounted in a limited space, use two different service bands (T-DMB and DVB-H) and independently operate for the two service bands to achieve high-quality mobile broadcasting services. Accordingly, various mobile broadcasting services can be provided using a single antenna and the product values and reliabilities of the resonance frequency variable type antenna of the invention and mobile terminals including the resonance frequency variable antenna of the invention can be improved. |
