ANTENNA DEVICE OF PORTABLE WIRELESS TERMINAL

摘要

PURPOSE: An antenna device of a portable wireless terminal is provided to form antenna patterns on thin film-type antenna sheets inserted between a keypad and a main board, or to form the antenna patterns on an inner side of a silicon keypad, thereby realizing an easy mounting process. CONSTITUTION: A cover(455) is mounted on a main board(457) built in a terminal. On the cover(455), a silicon keypad(451), the first antenna sheet(460a), a flexible keypad printed circuit(453), and the second antenna sheet(460b) are sequentially accumulated. The silicon keypad(451) is installed so that many key tops are protruded to an upper side of a terminal body, and is located in the highest position of a keypad(405) and an antenna device. The flexible printed circuit(453) has plural contact portions(453a) for generating an electric signal(S) inputted to the main board(457) according to operations of each key button comprised on the silicon keypad(451). The electric signal(S) is inputted to the main board(457) through a predetermined data cable(453b).
