Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] see figure 2 , this embodiment provides a slot antenna, the slot antenna includes: a floor 101, a coupling piece 102 and a feeding point 103;

[0028] One side of the floor 101 forms a semi-closed grooved area 104;

[0029] The coupling piece 102 is located in the semi-closed slot area 104, and forms a gap with the bottom wall 104a and the side wall 104b of the semi-closed slot area;

[0030] Wherein, the edge of the semi-closed slotted area 104 opposite to the opening of the semi-closed slotted area 104 is called the bottom wall 104a, and the edge of the semi-closed slotted area 104 extending from the bottom wall 104a to the two flanks is called the side wall 104b;

[0031] The feeding point 103 is located in the gap formed ...

Abstract

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.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a slot antenna, a parameter adjustment method and a terminal thereof. Background technique [0002] Wireless terminals, especially fixed WLAN (Wireless Local Area Network, wireless local area network) AP (Access Point, access point), WIMAX (Worldwide Interoperability for Microwave Access, global interoperability for microwave access) terminals, wireless fixed stations, etc., need An omnidirectional radiation, small volume antenna. [0003] At present, there is an antenna formed by opening a slit in the middle of the floor, called a slot antenna. see figure 1 , the typical shape of the slit is elongated, the length is about half a wavelength, and the slit is generally located in the middle of the floor, surrounded by the floor. There is a radio frequency electromagnetic field excited on the gap, and the electromagnetic wave is radiated into the space. After measuring, its horizontal pla...
