Antenna device and electronic device

Abstract

The invention provides an electronic device. The electronic device comprises a metal frame and a plurality of radio frequency sources. The metal frame is provided with a plurality of slits, the plurality of slits divide the metal frame into a plurality of independent frame segments, and the plurality of frame segments are used as antenna bodies and support frequency bands of a plurality of communication systems; wherein at least three frame segments support the 5G frequency band, at least one of at least three frame segments supporting the 5G frequency band supports the LMHB frequency band of the LTE at the same time, and except at least three frame segments supporting the 5G frequency band, at least one frame segment supports the LMHB frequency band of the LTE; and at least one frame section of an LMHB frequency band supporting LTE and at least three frame sections supporting the 5G frequency band except for the at least three frame sections supporting the 5G frequency band are used for realizing an NSA system of the 5G frequency band. The invention further provides an antenna device. According to the invention, the 5G NSA communication system is realized mainly through the metal frame, the antenna performance is improved, and the cost is reduced.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an antenna device and terminal equipment. Background technique [0002] At present, with the popularity of full screens and curved screens, there is less and less headroom for antennas. Due to the increase in frequency bands such as 5G, the number of antennas is more than that of 4G LTE, resulting in difficulties in antenna layout and reduced efficiency. Currently, metal frame antennas are often used to solve the problem of more antenna requirements and less headroom. However, the current design of the metal frame antenna is not very reasonable. For example, the number of antennas that can be made in the existing middle frame is limited, and more antennas need to be added inside the device in addition to the metal frame antenna. However, in Adding more antennas inside the device affects antenna performance and increases costs. Contents of the invention [0003] The p...
