Method for realizing terminal antenna, terminal antenna and terminal thereof

摘要

Provided is a method for implementing a terminal antenna, including: welding a metal shell for fixing a side key on a ground of a printed circuit board; dividing the ground of the printed circuit board into a first ground and a second ground, connecting the first ground with the second ground by at least one first isolating unit, the first ground being welded with the metal shell, and a length of the first ground being ¼ of a wavelength of a radio operating frequency band, and connecting the first ground with an antenna receiving/transmitting unit, thereby implementing a terminal antenna by taking the first ground as a radiator. The present invention also provides a corresponding terminal antenna and a terminal thereof.

1. A method for implementing a terminal antenna, comprising:
welding a side key onto a ground of a printed circuit board, PCB, by a metal shell for fixing the side key; wherein the part of PCB welded with the side key and the metal shell of the side key collectively form a first ground, and a length of the first ground being ¼ of a wavelength of a radio operating frequency band; a ground on the PCB except the first ground form a second ground; connecting the first ground with the second ground by at least one first isolating unit, wherein the first isolating unit is used to preventing the radio signal of an operating frequency band from being interfered, and meanwhile avoiding the signals of a non-operating frequency bands from being radiated out; connecting the first ground with an antenna receiving/transmitting unit; connecting the first ground to a corresponding side key signal wire by a second isolating unit, wherein the second isolating unit is configured to avoid the side key signal wire interfering with the first ground; thereby implementing the terminal antenna by taking the first ground as a radiator.
