<p>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 1/4 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. Since the side key is located outside a terminal and has a good radiation effect, a currently existing terminal standard accessory- side key - is utilized and functions as an antenna based on the antenna theory in the present invention without influencing the functions of the side key itself, thereby saving space effectively and reducing costs.</p> |
