Abstract: A mobile terminal including a body having a display unit mounted on a front surface of the body; a ground frame located on a back surface of the display unit and supporting the display unit; a first radiation element mounted on the body below the ground frame and configured to radiate an electromagnetic wave comprising a main lobe radiating in a backward direction of the mobile terminal toward a back surface of the body and a sub lobe radiating toward the front surface of the body; a metal plate disposed below the first radiation element and configured to reflect the electromagnetic wave comprising the main lobe in a forward direction to cause a surface wave along the ground frame and increase a size of the sub lobe radiating toward the front surface of the body; and a controller configured to apply power to the first radiation element to control the electromagnetic wave to be radiated.

Abstract: A mobile terminal includes patch antennas forming an array, an integrated circuit (IC) controlling transmission and reception of radio signals of the patch antennas, and a case disposed to cover the IC, wherein the case includes: a base forming an appearance, a heat dissipation sheet attached to an inner surface of the base to dissipate heat generated in the IC and having an opening corresponding to the patch antennas, and a dielectric disposed to cover the opening and formed of a dielectric material to allow radio signals from the patch antennas to be radiated to the outside of the case.

Abstract: The present invention discloses a method of transmitting signal by a terminal. The method comprises determining a direction of at least one antenna based on power loss tolerance of the signal and angle tolerance of the at least one antenna; and transmitting the signal based on the direction of the at least one antenna, wherein the power loss tolerance of the signal is determined at maximum of 2 dB.

Abstract: When a terminal aggregates three downlink carriers by using the carrier aggregation (CA) of the LTE-A technology and transmits an uplink signal on two uplink carriers while aggregating two uplink carriers, a harmonic component and an intermodulation distortion (IMD) component are generated, thereby influencing a downlink band of the terminal itself. Therefore, the present specification presents a scheme therefor.
