The footsteps of 5G (the fifth generation mobile communication) are getting closer and closer, and the new challenges to the antenna design of mobile phones are becoming more and more urgent. Recently, vivo and Qualcomm announced the successful cooperation in developing a 5G millimeter-wave antenna array for mobile phones and integrating it into vivo. Real machine, and complete the air interface performance measurement of the whole machine.
Dr. Huang Xuanqu, the antenna technical director/chief antenna expert in charge of the pre-research team of vivo antenna, said: "vivo is from WiGig (wireless gigabit, IEEE? 802. 1 1ad) Then to 5G millimeter wave, the continuous research and practice in the research and development of millimeter wave antenna for mobile phone shows that vivo attaches importance to millimeter wave antenna technology and 5G technology, and the successful research and development of 5G millimeter wave antenna array for mobile phone marks that vivo has taken a solid step forward in the technical accumulation and industry leading position in the design of millimeter wave antenna for mobile phone.

Currently 3GPP? For the millimeter wave band planned by 5G, its frequency starts from 24.25GHz. For users, the high working frequency of millimeter wave leads to large bandwidth, which can realize high-speed data transmission and help the peak data transmission rate of 5G reach 10~20? Gbps, which is today's 4G? The peak data transmission rate of LTE is 10~20 times, so it has obviously better wireless experience for AR, VR, AI, UHD (Ultra HD) image transmission and other applications. But at the same time, due to the high working frequency of millimeter wave, the energy loss and shielding effect of millimeter wave in propagation have been greatly improved compared with electromagnetic waves in common frequency bands of mobile phones today. Therefore, to deal with the millimeter wave band, we need to have a design concept and scheme different from the current mobile phone antenna, in order to achieve better wireless communication quality.
Dr. Huang Xuanqu believes: "For mobile phone antenna design, from 1G to 5G sub-6? GHz is basically an increase in quantity (such as the number of frequency bands and antennas), which means the refinement and optimization of antenna design, which means the evolution of tactics; Millimeter-wave antenna design is a qualitative leap for mobile phone antennas (such as array design and beamforming), that is, a brand-new positioning of antenna design, that is, a strategic revolution. So the technology and fineness of millimeter wave antenna design for mobile phones can be imagined to be better than today and 5G? Son 6? The antenna design of GHz is obviously high. "
Dr. Huang Xuanqu also shared: "vivo actively sorts out relevant patents, publishes international academic articles on millimeter-wave antenna technology, and meets the upcoming 5G era more comprehensively and solidly. After successfully completing the design and performance test of millimeter-wave antenna for 5G mobile phones, there will soon be the next round of new design and new achievements of millimeter-wave antenna for 5G mobile phones, which will help and contribute to the wireless experience of future users."
