1. An electronic device comprising:
an antenna disposed on a substrate disposed inside the electronic device and operable to resonate in a plurality of frequency bands; and
a feeding unit disposed on the substrate and composed of a feeding line feeding a signal to the antenna and ground lines operating as a ground,
the antenna including:
a first metal pattern connected to the feeding line, the first metal pattern including a first sub pattern and a second sub pattern; and
a second metal pattern connected to the ground lines, the second metal pattern including a third sub pattern,
wherein the first sub pattern and the third sub pattern are disposed on opposite sides with respect to the second sub pattern,
wherein the third sub pattern connected to the ground lines is disposed between the second sub pattern and the ground lines,
wherein the first metal pattern and the second metal pattern of a first radiator each have a slit of a predetermined length and width, and
wherein the first metal pattern further includes a matching stub pattern formed perpendicular to the slit of the first metal pattern, and a width of the matching stub pattern is smaller than a width of the feeding line.
