Problems solved by technology

For example, the bandwidth of the patent [CN108493600A] can only cover 3.4-3.6GHz, which cannot be applied to the metal frame environment, and 8 antennas need to be deployed in 8 positions; the patent [CN108565544A] increases the bandwidth to 3.3-5GHz, but it still cannot be applied Metal frame environment, and 8 locations need to be deployed

Abstract

A capacitively-decoupled broadband 5G MIMO mobile phone antenna comprises a metal floor, a metal frame and one or more sets of integrated dual-antenna assemblies. The metal floor is provided with oneor more floor slots at the edge, and the integrated dual-antenna assemblies are installed in the floor slots in a one-to-one correspondence manner. The metal frame is a closed connection structure with an even number of frame slots, and each set of integrated dual-antenna assembly corresponds to two frame slots. Each integrated dual-antenna assembly contains a first feeding branch, a second feeding branch and a decoupling assembly, and the decoupling assembly can be a lumped capacitor or a distributed capacitor. The 5G MIMO antenna designed by the capacitive decoupling technology has the advantages of broad band, high efficiency, small size, low headspace, compatibility with a metal frame and dual-antenna integration, and is suitable for various small mobile terminals represented by mobilephones.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a MIMO antenna, in particular to a capacitively decoupled broadband 5G MIMO mobile phone antenna. Background technique [0002] With the explosive growth of mobile user data volume, people put forward higher requirements on the rate, capacity and delay of mobile communication. The fifth generation (5G) mobile communication system begins to further improve the throughput of the mobile communication system through more antennas (MIMO technology) or wider bandwidth (millimeter wave technology). At present, deploying about eight 5G low-band MIMO antennas in mobile terminal devices such as mobile phones has become a mainstream solution in the industry. In the 15.5.0 version of the 5G wireless specification released in April 2019, the international 3GPP organization raised the global common 5G low frequency band from below 6GHz (Sub-6GHz) to below 7.125GHz. [0003] With the pursuit o...
