Problems solved by technology

[0003] Among the existing antennas, the MHB (medium-high frequency) antenna and the N77 antenna share a radiator to save space. The MHB antenna and the N77 antenna are integrated on the frame of the mobile terminal, and the wifi5G antenna is set near the frame. However, this setting In the method, the MHB antenna and the N77 antenna only use half of the frame, and the bandwidth of the covered frequency band is narrow, which is not enough to cover the N77 frequency band; in order to improve this situation, a parallel branch can be added to the N77 antenna. Resonance, broaden the bandwidth of the frequency band, but due to the reverse current between the parallel branches and the frame, there will be an efficiency pit near 3.8GHz, the worst point is -7.5dBi

Embodiment Construction

[0046] In order to make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0047] In order to facilitate the understanding of the antenna provided in the embodiment of the present invention, and to facilitate the understanding of the antenna provided in the embodiment of the present invention, first explain the state of antenna performance detection. The antenna performance detection adopts the free space (FS) state. At this time, the mobile terminal Place directly without contact with human body. Secondly, the antenna provided by the embodiment of the present invention can be a combination of two sub-antennas, or a combination of three sub-antennas, or a combination of more than three sub-antennas. Although the number of sub-antennas is different, the frequency band bandwidth of the antenna is different. The principle of stretching...

Abstract

The invention provides an antenna and a mobile terminal. The antenna comprises a first sub-antenna and a second sub-antenna, and radiators of the first sub-antenna and the second sub-antenna share a first branch, and the radiators of the first sub-antenna and the second sub-antenna further comprise a second branch. At setting, the second branch is electrically connected with the first branch, thesecond branch and the first branch are intersected at a set angle, and the ratio of the length of the second branch to the wavelength of a specific working frequency is within a set threshold value, wherein the specific working frequency is within the working frequency band of the second sub-antenna. The second branch is arranged to be electrically connected with the first branch and intersect with the first branch at the set angle, at the same time, the length of the second branch is limited, so that the resonance formed by the second branch is compatible with a half mode of the first branch,the frequency band width of the antenna is broadened. Moreover, a reverse current between the first branch and the second branch can be reduced, an efficiency pit is shallow, and further the performance of the antenna is improved, and the communication effect of the antenna is improved.

Description

Technical field [0001] This application relates to the field of communication technology, and in particular to an antenna and a mobile terminal. Background technique [0002] With the development of information technology, 5G networks have a theoretical peak transmission speed of up to tens of Gb per second, and the transmission advantage of being hundreds of times faster than 4G networks has become increasingly popular. In order to meet the transmission requirements of 5G networks, 5G mobile terminals need to be equipped with more antennas (N77, N78, N79) in a limited space and cover a wider frequency band. [0003] In the existing antennas, the MHB (medium and high frequency) antenna and the N77 antenna share a radiator to save space. The MHB antenna and the N77 antenna are designed on the frame of the mobile terminal, and the wifi5G antenna is set near the frame, but this setting In the method, the MHB antenna and the N77 antenna only use one-half mode of the frame, and the ban...
