PURPOSE: An antenna is provided to secure a current path by forming a first patch into a loop form. CONSTITUTION: An antenna comprises a ground part(152), an antenna patch(150), and a dielectric part. The antenna patch comprises a first and a third patch(160,170,180). The first patch is connected to the ground part and a feeding part with a PIFA(Planar Inverted-F Antenna) mode. A second patch is extended from the first patch. The second patch resonates in a first frequency band. The third patch is extended from the second patch. The third patch resonates in a second frequency band. The dielectric part supports the antenna patch.
