Abstract

The present invention discloses a wireless communication module, comprising a substrate; at least one wireless module, disposed on the substrate; and a module which does not emit wireless signals can be disposed on the substrate as well. The wireless communication module forms a compact structure and removes the need for RF shielded coaxial cables within the communication module. The present invention further discloses a portable device, which comprises a display part comprising a communication module; and a host part coupled to the display part; wherein the communication module is deposited on top of display part for better reception.

Claims
