The mobile phone with the wireless communication module antenna has the advantages of simple structure, low cost, convenient operation and the like a wireless mobile communication module antenna The present module relates to an electronic communication device, in particular it relates to a wireless communications module housing made of metal antenna phone. Now the phone design diversity, material applications are diverse, but generally will be designed to be partially metal texture emergent machine. And now the phone's features are also increasingly complex, in addition to the basic function of wireless communication, short-range wireless applications, and broadcasting style is also very common, common Bluetooth, WIFI in the phone, FM radio these various standard modules. These basic architecture and functions implemented in that the chip-level circuit design and electromagnetic energy radiated into the space and the electromagnetic energy receiving device antenna design from the space. According to the antenna theory, the efficiency of the antenna and the surrounding environment are closely related. The impact of general metal housing of the antenna are negative, how to reduce the negative impact of this factor becomes favorable or become the subject of our study. The deficiencies of the prior art, the present module aims to solve the existing mobile phone designs and function modules internal wireless antenna design contradiction to provide mobile metal shell member made utilizing a wireless communication module antenna
