Electronic device having antenna

A mobile terminal that changes in size, the mobile terminal comprising:

• a first metal housing including a left side surface and a right side surface defining the exterior of the mobile terminal,
• a second metal housing including a left side surface, a right side surface, and a bottom side surface defining the exterior—each of a first conductive member and a second conductive member of the second metal housing includes a first sub member disposed on the bottom side surface and a second sub member disposed on the left or right side surface—;
• a first printed circuit board (PCB) having a wireless communication unit;
• a second PCB electrically connected to the first PCB;
• a third PCB electrically connected to the second PCB;
• and
• a display including a first region that is exposed to a front surface in a retracted state of the mobile terminal, and a second region that is an expanded region exposed to the front surface in an expanded state of the mobile terminal,
• wherein the left side surface of the first metal housing and the second sub member of the second metal housing overlap each other, and the overlapped first metal housing is not exposed to the exterior while the second sub member is exposed to the exterior,
• a feed portion and a ground portion are connected from the second PCB to a first portion of the first metal housing, and
• a contact portion having tension is disposed between the first metal housing and the second sub member.
