Problems solved by technology

However, the inventors of the present invention found that the RF switch or tuner will introduce certain device losses and lose part of the antenna performance; and when multiple antennas are divided into frequency bands, the multiple antennas will not only occupy more area, but also increase the complexity of stacking. degree, it will also introduce the problem of isolation between multiple antennas

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each implementation manner of the present invention, many technical details are proposed in order to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in the present invention can also be realized.

[0019] A first embodiment of the present invention relates to an antenna.

[0020] Such as figure 1 As shown, the antenna includes a feed point 1, a ground point 2, a low-frequency antenna part and a high-frequency antenna part (not shown in the figure). The low-frequency antenna part includes a first low-frequency branch...

Abstract

The invention relates to the field of communications, and discloses an antenna and a mobile terminal. The antenna comprises a feed point, a ground point, a first low frequency branch, a second low frequency branch, a first high frequency branch and a second high frequency branch; the first low frequency branch and the second low frequency branch are connected with the ground point; the first high frequency branch and the second high frequency branch are connected with the feed point; the tail end of the first low frequency branch and the tail end of the second low frequency branch are away from each other; the second low frequency branch surrounds the first high frequency branch and the second high frequency branch, and the second low frequency branch and the first high frequency branch and the second high frequency branch form a capacitive feed mode. Accordingly, communication full band covering under a single antenna single state is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to an antenna and a mobile terminal. Background technique [0002] With the rapid development of communication technology, LTE (Long Term Evolution, Long Term Evolution) requires antennas to cover wider and wider frequency bands, but the low frequency (698-960MHz) and high frequency (LTE band11&21) frequency bands are more difficult to achieve. In the prior art, the above-mentioned low frequency and high frequency are usually realized by adding a radio frequency switch (RF switch) or a tuner (tuner) in different states, or through multiple antennas in frequency bands. However, the inventors of the present invention have found that the RF switch or tuner will introduce certain device losses and lose part of the antenna performance; and when multiple antennas are divided into frequency bands, the multiple antennas will not only occupy more area, but also increase the complexity of stacking. ...
