Abstract (en)
This application belongs to the field of antenna, and discloses a slot antenna, a terminal and a method for adjusting a parameter of the slot antenna. The slot antenna includes a board, a coupling chip and a feed point. A semi-closed slot area is formed on one side of the board. The coupling chip is located in the semi-closed slot area, and forms a slot with a lower wall and a side wall of the semi-closed slot area. The feed point is located in the slot formed between the coupling chip and the side wall. The method includes: adjusting at least one of the size of the slot, the size of the semi-closed slot area, the size of the coupling chip, and the number of layers of the coupling chip so as to obtain the corresponding resonant frequency and bandwidth. The terminal includes the slot antenna. The present invention enables the uniform distribution of the current on the board, thus achieving better omni-directional radiation feature, and the antenna size is smaller, thus occupying smaller area on a baseboard and leaving more area for other components.
