Embodiment Construction

[0013] Such as figure 1 As shown, it is a schematic structural diagram of the multi-feed antenna 20 in an embodiment of the present invention. In this embodiment, the multi-feed antenna 20 is applied to an electronic device 100 (such as figure 2 shown), such as mobile phones, tablets, etc.

[0014] The multi-feed antenna 20 includes an antenna body 21 , several antenna feed points disposed on the antenna body 21 , and several antenna ground points disposed on the antenna body 21 . In this embodiment, the several antenna feed points at least include a first antenna feed point 221 disposed at one end of the antenna body 21 and a second antenna feed point 221 disposed between two ends of the antenna body 21. The input point 222 includes at least a first antenna ground point 231 disposed between two ends of the antenna body 21 and a second antenna ground point 232 disposed at the other end of the antenna body 21 .

[0015] In this embodiment, the plurality of antenna feeding p...

Abstract

The invention provides a multi-feed antenna applied to an electronic device. The multi-feed antenna comprises an antenna body, a plurality of antenna feed points arranged on the antenna body and a plurality of antenna grounding points also arranged on the antenna body. The plurality of antenna feed points at least comprise a first antenna feed point arranged at one end portion of the antenna body, and a second antenna feed point arranged between the two end portions of the antenna body. The plurality of antenna grounding points at least comprise a first antenna grounding point arranged between the two end portions of the antenna body, and a second antenna grounding point arranged at the other end portion of the antenna body. The plurality of antenna feed points and the plurality of antenna grounding points are distributed on the antenna body in the staggered manner. The antenna body is provided with a plurality of radiating elements corresponding to a plurality of frequency bands and positioned between the plurality of antenna feed points and the plurality of antenna grounding points. The multi-feed antenna is simple in structure, and the full-band wireless transmission function is realized only by means of one antenna. Therefore, the number of antennas is effectively reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an electronic device and a multi-feed antenna thereof. Background technique [0002] As electronic devices have more and more communication functions, a single antenna can no longer meet people's needs for wireless communication. Therefore, many electronic devices are equipped with multiple antennas to receive different wireless signals, such as GSM, WIFI and other signals. However, multiple antennas will occupy a large area, and there is a problem of mutual interference, and the cost is also high. Contents of the invention [0003] In view of this, it is necessary to propose an electronic device and its multi-feed antenna to solve the above problems. [0004] A multi-feed antenna is applied to an electronic device. The multi-feed antenna includes an antenna main body, several antenna feed points and several antenna ground points arranged on the antenna main body. The ...
