Abstract:
1. A mobile terminal, comprising: a terminal main body formed with an accommodation chamber for accommodating a battery; a cover combined with the main body to cover the accommodation chamber and formed with a conductive material to transmit and receive radio electromagnetic waves; a circuit board formed with an electrical ground to process a signal corresponding to the radio electromagnetic waves; a feed connection portion electrically connecting the circuit board with the cover to allow the circuit board to feed power to the cover; and a ground connection portion electrically connecting the cover with the electrical ground to make a ground to the cover, wherein the ground connection portion comprises a first and a second ground connection portion disposed at positions separated from each other, wherein the first and second ground connection portions are disposed adjacent to opposing sides of the cover, respectively, wherein the feed connection portion is disposed adjacent to one of the first and second ground connection portions, wherein the feed connection portion, the cover, the first ground connection portion and the electrical ground are sequentially connected such that a part of the cover located between the feed connection portion and the first ground connection portion becomes a radiator of a loop antenna, and wherein the feed connection portion is disposed to be adjacent to the second ground connection portion such that the current supplied from the circuit board is transferred to the cover and the current circulated on the cover then enters the circuit board through the second ground connection portion.
