Abstract: An antenna device of a portable terminal is provided. The device includes a main board, a bar antenna, and a connector. The main board includes a feeding portion for feeding electricity and a grounding portion for grounding. The bar antenna is movable while being electrically connected to the feeding portion so as to protrude to an outside of the portable terminal or to be inserted into the inside of the portable terminal. The connector electrically connects the grounding portion of the main board to the bar antenna only when the bar antenna is completely inserted into the portable terminal.

Abstract: Disclosed is an antenna using a reactive element that is capable of individually controlling the respective resonance frequencies and resonance bandwidths. The antenna includes a radiator electrically coupled with a feeding point, a first reactive element electrically coupling a first point and a second point of the radiator, and a second reactive element electrically coupling a third point and a fourth point of the radiator. Here, the reactive elements are each coupled to the radiator in parallel, and because of the reactive elements, the antenna is made to have higher-order resonance frequencies that are not integer multiple in relation to a fundamental resonance frequency.
