Problems solved by technology

However, with the rapid development of mobile terminal technology, the screen-to-screen ratio of mobile terminals is gradually increasing, and the number of devices with internal metal structures is also increasing. In this way, the clearance area inside the body of the mobile terminal for designing antennas becomes increasingly larger. getting smaller

Embodiment Construction

[0032] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure.

[0033] Before describing in detail the antenna structure and signal radiation principles provided by the embodiments of the present disclosure, a brief introduction to the application scenarios involved in the embodiments of the present disclosure will be given first.

[0034] At present, similar to TDD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution) and FDD-LTE (Frequency Division Duplex Lon...

Abstract

The present disclosure relates to an antenna and a mobile terminal. The antenna is applied to a mobile terminal. The mobile terminal includes a first metal frame and a second metal frame. The length of the first metal frame is within a quarter of the wavelength of a specified frequency band; A metal frame includes a feed point, the feed point is located at a designated position on the first end of the first metal frame; the feed point is coupled to the first end of the first capacitive device, and the second end of the first capacitive device is connected to the conversion The first terminal of the switch is coupled, the second terminal of the conversion switch is coupled with the first terminal of the second capacitive device or the first terminal of the inductive device, and the second terminal of the second capacitive device or the second terminal of the inductive device is coupled with the first terminal The ground is coupled, and the second end of the first metal frame is coupled with the second ground point to form the first antenna; the second end of the second metal frame is coupled with the third ground point to form the second antenna. In this way, the antenna realizes the radiation of signals in various frequency bands without additionally adding other devices and antenna branches.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of mobile terminals, and in particular, to an antenna and a mobile terminal. Background technique [0002] With the advent of the 5G era, more and more frequency bands can be used for signal transmission, which makes the radiation requirements of antennas in mobile terminals continue to increase. For example, antennas are required to be able to radiate signals in existing frequency bands. , can also radiate signals in the 5G medium and low frequency millimeter wave frequency band, where the low frequency millimeter wave frequency band is commonly known as the Sub-6GHz frequency band. However, with the rapid development of mobile terminal technology, the screen-to-screen ratio of mobile terminals is gradually increasing, and the number of devices with internal metal structures is also increasing. In this way, the clearance area inside the body of the mobile terminal for designing antenn...
