An antenna and electronic equipment having the same are disclosed. The antenna comprises: a radiator electrically connected to a feeder, and radiating an electric wave; and one or more reinforcing circuits disposed in the radiator so as to uniformly distribute a current on at least one part of the radiator. The antenna can have a length much shortened than a wavelength of an operation frequency with maintaining the same efficiency, thereby being able to be mounted even in electronic equipment such as a terrestrial DMB terminal operated at a low frequency bandwidth,

A method of manufacturing a printed circuit board (PCB) having an embedded bare chip includes attaching a tape to one side of an insulated substrate having a penetration hole formed therein, and attaching the bare chip onto the tape inside the penetration hole such that electrode pads of the bare chip face the tape; filling up the penetration hole with a filler, and removing the tape; laminating a metal layer onto a surface of the filler and the insulated substrate from which the tape is removed; and forming electrode bumps by removing portions of the metal layer. The forming of electrode bumps further includes simultaneously removing portions of the metal layer and forming an circuit pattern on one side of the insulated substrate. The circuit pattern is formed directly on the upper side of the insulated substrate and the electrode bumps are formed on the surface of the electrode pads.
