A PRINTED CIRCUIT BOARD EMBEDDING AN ANTENNA AND A FILTER STRUCTURE AND A MENUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A printed circuit board embedded with an antenna and a filter structure and a manufacturing method of the same are provided to improve the matching property of a filter by forming a shunt capacitor pattern in an input/output line. CONSTITUTION: A first dielectric layer(200) is formed on a lowermost ground metal layer(100). A first metal layer is formed on the first dielectric layer. A capacitor pattern is formed on the first metal layer. A second dielectric layer covers the first metal layer. The second metal layer is formed on the second dielectric layer. An antenna pattern and an ultra-wideband filter pattern are formed on the second metal layer. A third dielectric layer(600) covers the second metal layer. An uppermost ground metal layer(700) is formed on the third dielectric layer.
