Mobile terminal

A bar type mobile terminal, comprising:

• a wireless communication unit including one or more components which permit wireless communications between the bar type mobile terminal and a wireless communication system;
• a plurality of antennas configured to transmit or receive radio signals;
• a metallic frame having a front side and a rear side, the metallic frame comprising:
• a base portion,
• an edge portion forming an appearance of the bar type mobile terminal and including a first slit and a second slit,
• an upper through hole disposed in an upper portion of the metallic frame, and
• a lower through hole disposed in a lower portion of the metallic frame;
• an upper non-metallic coupling disposed in the upper through hole of the metallic frame and the first slit, the upper non-metallic coupling being integrally formed with the metallic frame;
• a lower non-metallic coupling disposed in the lower through hole of the metallic frame and the second slit, the lower non-metallic coupling being integrally formed with the metallic frame;
• a window disposed on the front side of the metallic frame;
• a display module disposed at the front side of the metallic frame;
• a first waterproof layer disposed between the window and a front side of the edge portion of the metallic frame;
• a cover disposed on the rear side of the metallic frame;
• a first printed circuit board (PCB) disposed at the rear side of the metallic frame, wherein the wireless communication unit is mounted on the first PCB;
• a second waterproof layer disposed between the cover and a rear side of the edge portion of the metallic frame;
• and
• a thermal conductive member disposed between the wireless communication unit and the rear side of the metallic frame, the thermal conductive member being configured to transmit heat from the wireless communication unit to the metallic frame,
• wherein a portion of the metallic frame is configured to operate as ground,
• wherein a portion of the edge portion of the metallic frame is configured to operate as a radiator,
• wherein a portion of the edge portion of the metallic frame includes a top edge portion and a bottom edge portion,
• wherein the top edge portion of the metal frame includes a first radiator separated from a second radiator by the first slit,
• wherein the first radiator and the second radiator both operate in Long Term Evolution (LTE) frequency bands, and the first radiator operates in a different LTE frequency band than the second radiator,
• wherein the bottom edge portion of the metal frame includes a third radiator separated from a fourth radiator by the second slit, and
• wherein the third radiator and the fourth radiator both operate in LTE frequency bands, and the third radiator operates in a different LTE frequency band than the fourth radiator.
