Abstract
The disclosure provides an antenna feeding structure having a low frequency loop, an intermediate frequency loop, and a high frequency loop, and generates resonance between the inductance of the intermediate frequency loop itself and a capacitive element in the intermediate frequency loop, wherein the antenna feeding structure is configured to be able to adjust the resonance frequency using the area of the loop and the value of the capacitive element, thereby allowing the antenna to have a broadband characteristic, and further, making it possible to easily design an antenna having a desired band.
