Problems solved by technology

[0003] According to 3GPP TS38.101-2 5G terminal radio frequency technical specification and TR38.817 terminal radio frequency technical report, the 5G millimeter wave antenna needs to cover n257 (26.5-29.5GHz), n258 (24.25-27.25GHz), n260 (37-40GHz) and n261 (27.5-28.35GHz), while the current Qualcomm antenna modules on the market only cover the n257 frequency band (26.5-29.5GHz)
And conventional millimeter-wave antenna modules are either large in size and not suitable for mobile terminals; or have low gain, so their bandwidth and gain need to be improved

Abstract

The invention discloses a 5G millimeter wave antenna module and a mobile terminal. The antenna module comprises a support, wherein the support is provided with at least two antenna units, the antennaunit comprises a radiation main body, the radiation main body is provided with a main slot, the periphery of the main slot is provided with at least two branch slots, each branch slot comprises a first branch and a second branch, one end of the first branch is communicated with the middle part of the second branch, and the other end of the first branch is communicated with the main slot. The antenna unit can work in the frequency band ranges of n257 (26.5GHz to 29.5GHz), n258 (24.25GHz to 27.25GHz) and n261 (27.5GHz to 28.35GHz) by arranging the main slot and the branch slots on the radiationmain body, so that the coverage frequency band is wide; the antenna unit is simple in structure and low in test difficulty and beam management complexity; and the antenna unit occupies a small space and is suitable for mobile terminals such as mobile phones.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a 5G millimeter wave antenna module and a mobile terminal. Background technique [0002] 5G is the research and development focus of the global industry, and the development of 5G technology and the formulation of 5G standards have become the consensus of the industry. At the 22nd meeting of ITU-RWP5D held in June 2015, the International Telecommunication Union ITU identified three main application scenarios of 5G: enhanced mobile broadband, large-scale machine communication, and high-reliability and low-latency communication. These three application scenarios correspond to different key indicators. In the enhanced mobile bandwidth scenario, the user peak speed is 20Gbps, and the minimum user experience speed is 100Mbps. The unique high carrier frequency and large bandwidth characteristics of millimeter wave are the main means to achieve 5G ultra-high data transmi...
