| 主权项 | 1. An antenna device, comprising: a first member and a second member which form a first slot having an open part which is open and a connection part which is closed, one ends of the first and second member being connected with each other and other portions being spaced apart from each other; a feeding portion having one end connected to one of the first member and the second member such that the antenna device resonates in a first frequency band, and forming an electric field in the first slot; a feeding extension portion extending from the feeding portion such that the antenna device resonates in a second frequency band; and a third member extending and bending from end of the second member with a prescribed length, and forming a second slot between the first member and the third member, wherein the feeding portion is displaced at a first distance where an impedance is a predetermined ohm, when the first slot operates in a first frequency band, wherein the feeding extension portion extends from the feeding portion by a second distance so that an impedance can be a predetermined ohm, when the first slot operates in a second frequency band, wherein an opening of the first slot and an opening of the second slot are formed in direction opposite to each other, and wherein the second slot resonates at a third frequency adjacent to the frequency of the second frequency band so that the third member is configured to extend a bandwidth of the second frequency band. | ||
