BUILT-IN ANTENNA STRUCTURE OF MOBILE DEVICE CAPABLE OF REDUCING SIZE OF ANTENNA AND INCREASING RADIATING SURFACE

摘要

PURPOSE: A built-in antenna structure is provided to reduce the size of the antenna and achieve improved radiation pattern and efficiency of the antenna by increasing a radiating surface. CONSTITUTION: A built-in antenna structure comprises a carrier(122) spaced apart from a printed circuit board(110); a radiating plate(121) including a horizontal surface(121a) contacting the upper surface of the carrier and a vertical surface(121b) contacting the surface arranged vertically with the upper surface of the carrier, wherein the radiating plate has patterns(123) formed on the horizontal surface and the vertical surface; a feeding pin(124) for connecting the printed circuit board and the patterns so as to transmit the signal of the printed circuit board; and a ground pin for connecting the radiating plate to a ground unit so as to ground the radiating plate.
