Mobile terminal

A bar-type mobile terminal, comprising:

• a wireless communication unit configured to communicate wireless signals;
• a plurality of antenna devices correspondingly disposed at upper and lower portions of the mobile terminal and configured to transmit or receive radio signals;
• and
• a frame comprised of a metallic material and configured to form an upper side, a lower side, and lateral sides of an outer appearance of the mobile terminal,
• wherein the frame comprises:
• a first edge member and a second edge member disposed at an upper portion of the frame;
• a first slit defined between the first edge member and the second edge member;
• a third edge member and a fourth edge member disposed at a lower portion of the frame;
