2.AFR PrecisionThere is a mobile phone with a wireless communication module antenna; the mobile phone is connected with a metal rear cover; a metal battery cover of the mobile phone serves as the antenna; a shrapnel is designed on the battery cover; the input feed point of the FM antenna is designed on the circuit board of the mobile phone; and when the battery cover is covered, the shrapnel and the input feed point effectively are contacted with each other, and the function that the battery cover serves as the antenna can be realized. 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 phones 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 ante |
