PURPOSE: A PCB antenna which includes a via hole structure is provided to form a via hole and a sub slot in a radiation pattern formed among feeding lines to maximize isolation among the feeding lines, thereby miniaturizing an antenna module. CONSTITUTION: A PCB antenna(100) is composed of a dielectric substrate(110), a radiating unit(130), and a ground unit(150). The radiating unit and the ground unit are composed of copper, silver, gold, and aluminum. Via holes(137) are formed at a fixed interval along with the longitudinal direction of the radiation pattern of the radiating unit. A first feeding line and a second feeding line generate a coupling effect.
