Embodiment

[0028] Please refer to figure 1 , the present embodiment is an antenna system based on an all-metal back cover smartphone, which includes a metal back cover 1 and an integrated PCB board 2, the upper edge and the lower end edge of the metal back cover 1 are provided with a C-shaped gap 3, the metal back cover The upper part of the cover 1 separated by the slit 3 forms a C-shaped radiating body 4. The antenna system also includes several coupling units arranged on the integrated PCB 2 and coupled with the C-shaped radiating body 4. The slit 3 is provided with a communication The connecting piece 5 between the C-shaped radiating body 4 and the integrated PCB board 2 .

[0029] The integrated PCB board 2 is provided with a number of metal material modules (not marked in the figure), and the metal material modules include a rear camera 6, a front camera 7, an earpiece net decoration 8, and a corner area sticker with the rear camera 6. Combined radiation patch9. The coupling unit...

Abstract

The invention discloses an antenna system based on a smart phone with an all metal back cover. The antenna system comprises a metal back cover and an integrated PCB, wherein the upper edge and the lower edge of the metal back cover are each provided with a C-shaped clearance, the upper end of the metal back cover form a C-shaped radiation main body due to a part separated by the clearance, the integrated PCB is provided with a plurality of coupling units coupled with the C-shaped radiation main body, and the clearance is provided with a connecting piece communicating the C-shaped radiation main body with the integrated PCB. Due to the all metal back cover structure, the antenna system has an excellent radiation performance, and the radiation performance of each frequency of the antenna is improved while the metal back cover is more integral.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an antenna system based on an all-metal back cover smart phone. Background technique [0002] In the communication terminal mobile phone, the metal devices and metal wiring inside the mobile phone will be integrated into one body, forming a large metal reference body compared with the radiation body of the antenna, which is called the main "ground". The area (parallel to the screen plane of the mobile phone) with metal components (including metal components on the PCB board and metal devices such as cameras) around the antenna is called headroom. The full frequency band (824-960MHZ, 1710-2690MHZ) perfectly covers all frequency bands of mobile communications in the Asia-Pacific region, and can ensure that mobile phones work under various standards and frequency bands. The main material of the bottom shell of the mobile phone is made of metal, and it is only conv...
