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

Disclosed in this paper are a mobile terminal and a method for improving antenna performance of the mobile terminal. The mobile terminal includes: a PCB mainboard; a bracket for mounting an antenna, and the bracket is mounted on the PCB mainboard via a conductive connecting piece, and the bracket is connected with the mainboard ground of the PCB mainboard; an antenna mounted on the bracket and spaced from the connecting piece; and a parasitic branch connected with the connecting piece, and the parasitic branch is arranged beside the antenna and is spaced apart from the antenna, and the parasitic branch is used to improve the bandwidth and / or radiation beam direction 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 ground feed points are reserved on the motherboard PCB, that is, ground shrapnel, some are two, and some are more, mainly to facilitate the performance design of the antenna, that is: use the ground The shrapnel leads out the parasitic branch and the antenna separately, and the bandwidth of the antenna is widened and the radiation efficiency of the antenna is improved through the parasitic branch. [0003] Problems existing in the prior art: [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 g...
