The present invention relates to an antenna apparatus and a feeding structure thereof, which comprise a grounding unit and a feeding unit supplying a signal to the grounding unit. Provided are the feeding structure which includes a main resonance portion formed by connecting the grounding unit and the feeding unit; a resonance adding portion disposed between the grounding unit and the feeding unit to flow a signal; and at least one reactance element arranged in at least any one of the main resonance portion or the resonance adding portion, and the antenna apparatus having the same. According to the present invention, the reactance of the reactance element can be changed, thereby enabling to adjust a resonance frequency band of the antenna apparatus easily. |
