Chip antenna and mobile-communication terminal having the same

A mobile telecommunication terminal comprising:

• a chip antenna comprising:
• a dielectric block having opposing top and bottom surfaces and a plurality of side surfaces connecting the top and bottom surfaces;
• a first conductive pattern formed on at least one of the surfaces of the dielectric block and connected to an external feeding part;
• a second conductive pattern formed on at least one of the surfaces of the dielectric block to connect to the first conductive pattern, and having one end connected to an external ground part;
• and
• a third conductive pattern formed on at least one of the surfaces of the dielectric block, and spaced apart from the first and second conductive patterns at a predetermined distance to be capacitively coupled to the first and second conductive patterns, respectively, the third conductive pattern having a lower end connected to the external ground part;
• and
• a printed circuit board having the chip antenna mounted on one surface thereof, the printed circuit board comprising a tuning ground pattern formed on another surface opposing the one surface of the printed circuit board and having one end connected to a ground part to be used for tuning frequency characteristics of the chip antenna.
