Problems solved by technology

However, due to the limited space in electronic devices, if the size of the antenna is not small enough, it is difficult to adapt to the design specifications of today's smart electronic devices with large screens and narrow borders.
In addition, in the design of MIMO antennas, when several antennas operating in the same frequency band are jointly designed in a terminal device with limited space, the interference between antennas will become larger and larger due to the close distance between the antennas. That is, the isolation between antennas will be greatly increased
Moreover, it may also cause an increase in the envelope correlation coefficient (ECC) between multiple antennas, resulting in a decrease in data transmission speed.

Abstract

The embodiment of the invention provides electronic equipment. The electronic equipment comprises a first decoupling piece, a first radiator, a second radiator, a first feed unit, a second feed unit and a rear cover, wherein a first gap is formed between the first radiator and the second radiator; the first radiator comprises a first feeding point, and the first feeding unit feeds at the first feeding point; the second radiator comprises a second feeding point, and the second feeding unit feeds at the second feeding point; the first decoupling piece is in indirect coupling connection with the first radiator and the second radiator; and the first decoupling piece is arranged on the surface of the rear cover. According to the technical scheme provided by the embodiment of the invention, under the configuration that multiple antennas are compactly arranged, the antenna has the characteristic of high isolation in a designed frequency band, good radiation efficiency and low ECC of the antenna can be maintained, and good communication quality is achieved.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular to an electronic device including a multi-antenna structure. Background technique [0002] The rapid development of sub-6GHz multi-input multi-output (MIMO) antenna systems has been accelerated due to the continuous improvement of the transmission speed requirements of the fifth generation (five generation, 5G) mobile communication terminals. The sub-6GHz MIMO antenna system can arrange a large number of antennas on both the base station and the terminal, and perform multiple channel simultaneous data transmission on the same time domain (time domain) and frequency domain (frequency domain), which can effectively improve spectrum efficiency and greatly improve Data transfer speed. Therefore, it has become one of the development focuses of the next-generation multi-gigabit (multi-Gbps) communication system. However, due to the limited space in the electronic devi...
