Patent ID: 7170456

Claim:
A dielectric chip antenna structure, comprising: a printed circuit board on which an antenna is mounted, the printed circuit board having a feeding line formed in a predetermined pattern thereon for feeding and top and bottom planes which are short-circuited; a first metal conductor formed on the top plane of the printed circuit board, for feeding; a second metal conductor for short-circuiting the first metal conductor and a feeding part of the antenna and fixing the antenna; a third metal conductor for short-circuiting a grounding part of the antenna and fixing the antenna; a fourth metal conductor formed at the lateral side of the antenna along the longitudinal direction of the antenna to induce antenna resonance characteristic through antenna coupling effect between the antenna and the ground; circular or semicircular via holes formed in the top and bottom planes in such a manner as to penetrate the top and bottom planes to short-circuit the top and bottom planes, the sidewalls of the via holes being coated with a metal; a fifth metal conductor for connecting the top and bottom planes when the via holes are eliminated; and sixth and seventh metal conductors respectively formed on the top and bottom planes for forming the fourth metal conductor and control an input impedance of the antenna.
