Abstract: A mobile terminal, comprises: a case including a conductive metal part; a main board mounted inside the case and having a power supply part and a ground surface; a first antenna radiator disposed so as to be spaced from the power supply part to the first antenna radiator; a power supply line for electrically connecting the power supply part to the first antenna radiator and ground line for electrically connecting the ground surface to the metal part and the first antenna radiator, thereby preventing a decrease in the performance of an antenna since the formation of an electromagnetic field between the case of a metallic material and the main board can be minimized even if the metallic material is used for the case.

Abstract: An antenna apparatus includes: a first member ground-connected to a ground of a printed circuit board (PCB); a second member spaced from the first member in parallel, and configured to capacitive coupling-feed the first member so as to transmit and receive signals of a first frequency band; and a third member extending from the second member by a prescribed length, so as to have a bandwidth extending up to a second frequency band adjacent to the first frequency band.
