<p>A method for realizing a terminal antenna is provided. Metal shells for fixing side keys are welded on the ground of a printed circuit board. The ground of the printed circuit board is divided into a first ground and a second ground, where the first ground and the second ground are connected with each other by at least one of a first isolation unit. The first ground is welded with the metal shells, where length of the first ground is one quarter of the wavelength of a wireless work frequency band. The first ground is connected with an antenna receiving/transmitting unit. Thus, the terminal antenna is realized with the first ground as the radiator. A corresponding terminal antenna and a corresponding terminal are also provided. Since the radiation effect is very well because the side keys locate outside of a terminal, the method utilizes current existing terminal standard accessories-side keys combining with antenna theory to make the side keys be double as an antenna function without influencing own function of the side keys, so that the method effectively enables saving space and reducing cost.</p> |
