Portable terminal with antenna device for display element or display assembly including flexible functional region

A portable terminal is disclosed. The portable terminal comprises: a flexible display element or a display assembly including at least a partially flexible functional region; a first antenna element disposed at a first region on the display element; a second antenna element disposed at a foldable second region on the display element to face the first region; and a switch element configured to connect or disconnect the second antenna element, wherein, when the display element is folded or rolled, the first and second antenna elements partially overlap with each other and the switch element disconnects the second antenna element. The portable terminal with an antenna device described above can maintain a stable transmission/reception performance even in a folded or rolled state though the portable terminal is provided with the flexible display element or display assembly. Also, when a plurality of antenna elements are provided, the portable terminal can implement a MIMO antenna device, in which the antenna elements perform transmission and reception operations independently from each other, in a state where the flexible display element is spread.
