Abstract
A mobile terminal comprises a case; a main board packaged in the case; a signal supply unit packaged on the main board, supplying a radio signal; an antenna radiator packaged in the case, including a conductive material and transmitting and receiving a signal of a first frequency; an antenna tuner packaged in the case, including a conductive material; a feeding line located on the main board, having one end connected with the signal supply unit and the other end connected with the antenna radiator; and a tuning line located on the main board, having one end connected to the feeding line and the other end connected with the antenna tuner, wherein the tuning line and the antenna tuner compensate for impedance of the feeding line and the antenna radiator. The mobile terminal can prevent wireless communication performance from being deteriorated by impedance distorted by an external environment like that a body of a user approaches the antenna radiator.
