Claim Text:
1. An antenna apparatus, comprising: a radiating body; a feeding part for providing a signal for the radiating body and connected to the radiating body; a grounding part for grounding the radiating body and extended from the radiating body; a resonance addition part disposed between the feeding part and the grounding part; and a ground body connected to the grounding part and the resonance addition part, wherein the resonance addition part comprises at least one reactance device, wherein the reactance device comprises at least one of a capacitive device and an inductive device, wherein the reactance device is connected to the feeding part and the grounding part in parallel, wherein a first loop is formed by the feeding part and the resonance addition part and generates a first magnetic flux in a first frequency band, wherein a second loop is formed by the resonance addition part and the grounding part and generates a second magnetic flux in a second frequency range, wherein a third loop is formed by the feeding part and the grounding part and generates a third magnetic flux in a third frequency range, and wherein, in the second frequency range, a resonance is generated due to an inductance provided by the second loop and a reactance provided by the at least one reactance device such that the second magnetic flux mainly excites the radiating body.
