PRINTED CIRCUIT BOARD, ANTENNA, WIRELESS COMMUNICATION DEVICE AND MANUFACTURING METHODS THEREOF

摘要

Disclosed are a low-loss printed circuit board, a low-loss broadband antenna, and methods for manufacturing the printed circuit board and the antenna using a resin as a substrate material. A resin material (101) having a predetermined shape is manufactured in a forming step, and the resin material (101) is foamed in a foaming step, thereby forming a skin layer (111) and a foam section (112). Since the skin layer (111) does not permit plating to be deposited thereon, the skin layer (111) is removed in a conductor pattern shape in a skin layer removing step, and the foam section (112) inside is exposed. Plating is deposited on the foam section (112), which has anchor effects, by performing electroless plating in a conductor layer forming step, and a conductor layer (120) is formed.
