Wireless telecommunication device

摘要

A wireless telecommunication device is disclosed. The wireless telecommunication device includes a printed circuit board, an antenna, an insulating layer, and an electrostatic discharge layer. The antenna is electrically coupled with the printed circuit board for transmitting a wireless signal received or sent by the printed circuit board. The insulating layer is disposed between the printed circuit board and the electrostatic discharge layer. At least a clean area exists in the electrostatic discharge layer and the clean area is configured corresponding to the source area of high frequency noises on the printed circuit board. The purpose of the clean area is to create a leaking channel for high frequency noises and decrease the interference toward the antenna from high frequency noises.
