Problems solved by technology

[0004] Restricted by the PCB layout of the motherboard and the antenna clearance area, when a single ground shrapnel is reserved for the antenna, there is no additional circuit area to lay out the ground shrapnel feed points or ground traces that lead out to the parasitic stubs, so that the parasitic stubs cannot Connected to the main board ground, in this case, the performance of the antenna, such as the antenna bandwidth is not wide enough, is greatly limited

Abstract

The invention discloses a mobile terminal and a method for improving an antenna performance of a mobile terminal. The mobile terminal comprises a PCB, a support frame, an antenna, and a parasitic branch. The support frame for installing the antenna is installed on the PCB by a conductive connecting element and is connected with the main board of the PCB. The antenna installed on the support frame is separated from the connecting element. The parasitic branch connected with the connecting element is arranged at one side of the antenna at an interval and is used for improving the antenna bandwidth and / or radiation wave beam direction. According to the mobile terminal, connection with the main board is realized by connection of the parasitic branch and the fixed support, thereby realizing successful leading out of the parasitic branch; and then on the basis of the routing way of the parasitic branch, layout is carried out to increase the antenna bandwidth and guarantee the radiation efficiency of the antenna.

Description

Technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a mobile terminal and a method for improving the antenna performance of the mobile terminal. Background technique [0002] At present, in the antenna design of mobile terminals, a sufficient number of grounding feed points, that is, grounding shrapnel, are reserved on the motherboard PCB, some two, and some more, mainly for the convenience of antenna performance design, that is: use grounding The shrapnel separately leads out the parasitic branch and the antenna, and the parasitic branch is used to broaden the bandwidth of the antenna and improve the radiation efficiency of the antenna. [0003] Problems with existing technology: [0004] Limited by the PCB layout of the motherboard and the antenna clearance area, when the antenna is reserved for a single ground shrapnel, there is no extra circuit area to lay out the ground shrapnel feed points or ground traces that lead to ...
