Embodiment Construction

[0020] In order to better illustrate the present invention, the present invention will be described in detail with a preferred embodiment and with accompanying drawings, specifically as follows:

[0021] Such as figure 1 As shown, the metal frame mobile phone antenna provided by this embodiment is arranged on one side of the metal frame 400 of the mobile phone, and the side metal frame is provided with a first slit 401 and a second slit 402. Diversity antenna part 200 and WIFI antenna part 300 above. Wherein, the highest part of the main body of the antenna is 4 mm away from the upper surface of the PCB 100 . That is to say, looking at the PCB board from the side, the main part of the antenna is 4mm larger than the thickness of the PCB board.

[0022] Such as figure 2 , image 3 As shown, the diversity antenna part 200 includes a diversity antenna grounding branch 202 and a diversity antenna feeding part 201 connected to the PCB board 100, and the diversity antenna ground...

Abstract

The invention provides a metal frame mobile phone antenna, which is provided on one side of the metal frame slot and comprises a diversity antenna section and a WIFI antenna section provided on a PCB. The diversity antenna section comprises a diversity antenna grounding branch connected with the PCB and a diversity antenna feeding part, as well as a first diversity antenna feeding branch which is provided on the metal frame and is connected to a first branch parasitic in the diversity antenna. The WIFI antenna section includes a WIFI antenna grounding branch and a WIFI antenna feeding part connected with the PCB. The WIFI antenna feeding part is further connected with a first WIFI antenna feeding branch and a second WIFI antenna feeding branch. The metal frame mobile phone antenna of the invention, with the separate arrangement yet common grounding of a diversity antenna section and a WIFI antenna section, improves the isolation between the antennas, thereby ensuring good bandwidth and radiation performance of high and low frequencies of the diversity antenna and the WIFI antenna, and effectively reducing the mutual coupling between the diversity antenna and WIFI antenna.

Description

technical field [0001] The invention relates to the technical field of mobile phone antennas, in particular to a metal frame mobile phone antenna. Background technique [0002] At present, metal-textured mobile phones are generally favored by the majority of users, and smart terminals designed with metal frames have become a mainstream. The design of the metal frame brings great challenges to the research and development of the antenna. Accompanying it is the deterioration of the antenna system environment and the decline in performance, especially for the design of the small antenna on the top, two or more antennas are concentrated on the top, and the mutual coupling between the antennas greatly affects the performance of the antenna , resulting in greatly reduced diversity reception performance, GPS performance and WIFI performance. Contents of the invention [0003] The purpose of the present invention is to provide a metal frame mobile phone antenna to solve the prob...
