A PRINTED CIRCUIT BOARD ANTENNA FOR A PORTABLE TERMINAL USING MAGNETO-DIELECTRIC

摘要

A printed circuit board antenna for a portable terminal using magneto-dielectric is provided to decrease the size of a built-in antenna by depositing a ferrite film on an antenna pattern. A printed circuit board antenna includes a printed circuit board(10) on which components of portable terminal are mounted, an antenna pattern(20) patterned on the printed circuit board in a predetermined pattern to serve as a radiator, and a ferrite film(30) formed on the antenna pattern. The printed circuit board is made of RF4, and the antenna pattern is made of Cu. The ferrite film is formed by depositing magnetic material on the antenna pattern.
