Embodiment

[0028] Please refer to figure 1 This embodiment is an antenna system based on a smart phone with a metal back cover, which includes a metal back cover 1, an integrated PCB board 2. The upper and lower edges of the metal back cover 1 are both provided with a C-shaped gap 3, and the metal back The upper part of the cover 1 separated by the gap 3 forms a C-shaped radiating body 4. The antenna system further includes a number of coupling units arranged on the integrated PCB board 2 and coupled with the C-shaped radiating body 4. The gap 3 is provided with communication The connecting piece 5 of 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 shown in the figure), the metal material modules include a rear camera 6, a front camera 7, a handset net decoration 8 and a corner area attached to the rear camera 6 合的radiation patch9. The coupling unit includes a first coupling portion us...

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 field of communication technology, and in particular relates to an antenna system based on a smart phone with an all-metal back cover. Background technique [0002] In a communication terminal mobile phone, the metal components and metal traces inside the mobile phone will be connected as a whole, forming a larger metal reference body, called the main "ground" compared to the antenna's radiating body. The area (parallel to the plane of the mobile phone screen) with metal components (including metal components on the PCB board and metal components such as cameras) around the antenna is called clearance. The full frequency band (824-960MHZ, 1710-2690MHZ) perfectly covers all frequency bands of mobile communication in the Asia-Pacific region, and can ensure that the mobile phone works under various standards and frequency bands. The main body material of the bottom case of the mobile phone is made of metal, which is only convenien...
