5G millimeter wave module and mobile terminal with ceramic shell

Abstract

The invention discloses a 5G millimeter wave module and a mobile terminal with a ceramic shell. The 5G millimeter wave module comprises a ceramic dielectric resonator antenna and a PCB assembly; the PCB assembly is provided with a caliber coupling structure, and the ceramic dielectric resonator antenna abuts against the caliber coupling structure. The 5G millimeter wave module is excellent in performance, the radiation performance is not affected in the mobile terminal with the ceramic shell, the combined design of the 5G millimeter wave module and the ceramic shell is realized, and the 5G millimeter wave module is particularly suitable for the mobile terminal with the ceramic shell; the profile is low, the size is small, and the development trend of lightening and thinning mobile terminalequipment is met.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a 5G millimeter wave module and a mobile terminal with a ceramic case. Background technique [0002] As 5G is the research and development focus of the global industry, it has become an industry consensus to develop 5G technology and formulate 5G standards. At the 22nd meeting of ITU-RWP5D held in June 2015, the International Telecommunication Union ITU clarified 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 transmission rate. However, the s...

Problems solved by technology

[0003] At present, when the 5G millimeter wave module is placed in the real machine environment, the radiation performance will be reduced due to the influence of the material of the mobile phone case (plastic, metal, ceramic, etc.), and even the radio frequency circuit will not work.

For ordinary plastic mobile phones, after the 5G millimeter wave module is put in, the impact is small and can be ignored; for metal shell phones, many patents and papers have proposed various solutions; for high dielectric constant ceramic shell phones, At present, there is a lack of papers and patents to solve the attenuation of the radiation performance of millimeter wave modules in this environment
