Wireless electronic communication device

Abstract

The invention provides a wireless electronic communication device, comprising a metal frame body and a gap structure; the metal frame body is provided with a first antenna and a second antenna, the first antenna and the second antenna are spaced by a first preset distance, and the first antenna and the second antenna are respectively provided with a feed structure; the gap structure is arranged between the first antenna and the second antenna, and the extension distance of the gap structure in the width direction of the metal frame body is smaller than the width of the metal frame body. According to the embodiment of the invention, the isolation degree of the antenna can be improved, the mutual influence between the antennas can be reduced, and the index of an envelope correlation coefficient can be improved, so that the channel capacity of multi-input multi-output is improved, the transmission rate is increased, and meanwhile, the gap structure can be multiplexed; and more antennas can be formed on the basis that no extra space is added, thereby further improving the overall competitiveness of the product and the wireless communication experience of users.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a wireless electronic communication device. Background technique [0002] The fifth-generation mobile communication technology (5th-Generation, 5G) adds a new frequency band, and for higher data transmission rates, it needs to support higher-order multiple-input and multiple-output (Multiple-Input Multiple-Output, MIMO), such as 4*4MIMO may even support 8*8MIMO in the future, so the number of antennas required by wireless electronic communication equipment will increase significantly in the foreseeable future, even reaching more than ten antennas. So many antennas are integrated in wireless electronic communication equipment. This makes the isolation between the antennas an obvious challenge, and because the isolation between the antennas becomes worse, the radiation efficiency of each antenna is reduced, and the index of the Envelope Correlation Coefficient (ECC) i...
