Problems solved by technology

[0003] However, if during the debugging process, it is found that the position of each function pin needs to be adjusted or exchanged, the PCB board needs to be redone, or even the mold needs to be re-opened. The material preparation cycle is very long, which seriously affects the debugging progress.

Abstract

The invention discloses an antenna circuit and a mobile terminal. The antenna circuit comprises a plurality of elastic pins, a tuning switch, a radio frequency chip, a metal ground plate and a plurality of surface-mount positions; the tuning switch is connected with each elastic pin in the plurality of elastic pins; the radio frequency chip is connected with each elastic pin; the metal ground plate is connected with each elastic pin; and the plurality of surface-mount positions are arranged between the tuning switch, the radio frequency chip, the metal ground plate and each elastic pin, so that surface-mount elements are mounted at the surface-mount positions. The surface-mount elements are mounted at the different surface-mount positions, so that the effect of each elastic pin can be changed, and therefore, the remanufacture of a PCB is not needed, and debugging progress is improved.

Description

technical field [0001] The present application relates to the field of communication, in particular to an antenna circuit and a mobile terminal. Background technique [0002] In the design and development process of electronic products such as mobile phones, each antenna spring used by the antenna (that is, the connection spring between the circuit on the PCB and the antenna FPC) has switch points, feed points, ground points, and parasitic points. Before opening the mold or making the PCB board, it is necessary to fix the position of each spring pin for PCB board line drawing and antenna structure design. [0003] However, if during the debugging process, it is found that the position of each functional pin needs to be adjusted or exchanged, the PCB board needs to be redone, or even the mold needs to be re-opened. The material preparation cycle is very long, which seriously affects the debugging progress. Contents of the invention [0004] The embodiment of the present ap...
