Network communication device having electromagnetic shielding function

Abstract

A network communication device has a circuit board, a network communication chip, an antenna, and a metal cover. The circuit board has a first surface and a second surface opposite to each other. An interior of the circuit board has a ground layer. An edge of the first surface has a ground ring. The ground ring surrounds the first surface and is electrically connected to the ground layer. The network communication chip is disposed on the first surface. The antenna is electrically connected to the circuit board. The metal cover has an annular support rib. The circuit board is disposed on the annular support rib with the first surface facing the metal cover. The ground ring is in physical contact with and electrically connected to the annular support rib.
