Abstract (en)
[origin: KR20150027682A] According to an embodiment of the present invention, provided is an electronic device including a processor and an antenna device. The antenna device includes: a power feeding unit; a first radiation unit electrically connected to the power feeding unit; and a switching element including a first terminal electrically connected to a first portion of the first radiation unit, and a second terminal electrically connected to a second portion of the first radiation unit. The processor uses a first resonance frequency band when the switching element is opened and uses a second resonance frequency which is different from the first resonance frequency band when the switching element is closed. The electronic device may be variously modified.
