Abstract:
1. A mobile telecommunication terminal, comprising: a chip antenna comprising: a printed circuit board having the chip antenna mounted on one surface thereof, the printed circuit board comprising a tuning ground pattern formed on a surface opposing the one surface of the printed circuit board, the tuning ground pattern having one end connected to the external ground part for tuning frequency characteristics of the chip antenna, wherein a coupling capacitance between the first and second conductive patterns is greater than a coupling capacitance between the first and third conductive patterns, wherein a length of the third conductive pattern is determined to adjust the impedance matching of the chip antenna and to result in a corresponding variation in a resonant frequency of the chip antenna, and wherein the coupling capacitance between the first and third conductive patterns is greater than a coupling capacitance between the second and third conductive patterns.
