The pace of 5G (5th generation mobile communication) is getting closer and closer, and the new challenges for the design of mobile antenna are becoming more and more urgent. Recently, Vivo and Qualcomm announced that they have successfully collaborated to develop a 5G millimeter wave antenna array for mobile phones and to Integrate into vivo real machine, and complete aircraft air interface performance measurement.

Antenna Technical Director/Chief Antennae Dr. Huang Wei, who is in charge of the vivo antenna pre-research team, said: 'vivo' from WiGig (ie, wireless Gigabit, IEEE 802.11ad) to 5G millimeter wave, continues to specialize in mobile phone millimeter wave antenna research and development. Research and practice illustrate the importance of vivo for millimeter-wave antenna technology and 5G technology. The successful development and production of mobile phone 5G millimeter-wave arrays mark the technical accumulation and industry leadership of vivo in the design of mobile millimeter wave antennas. Go forward again and take a solid look.
At present, 3GPP is planning on the millimeter waveband for 5G. Its frequency starts from 24.25 GHz. For users, due to the large bandwidth due to the high millimeter wave operating frequency, high-speed data transmission can be achieved, which helps the 5G peak data. The transmission rate reaches 10~20 Gbps, which is 10~20 times that of today's 4G LTE peak data transmission rate. Therefore, for applications such as AR, VR, AI, and UHD (Ultra High Definition) image transmission, there is a significantly better wireless experience. However, at the same time, due to the high operating frequency of millimeter waves, the energy loss and shielding effects encountered by millimeter waves during propagation are greatly increased compared with the electromagnetic waves commonly used in today's mobile phones. Therefore, in response to the millimeter wave band, there is a need for mobile phones. Different antenna design concepts and solutions to achieve better wireless communication quality.
Dr. Huang Yu thinks: 'For mobile phone antenna design, sub-6 GHz from 1G to 5G is basically an increase in the amount (eg, number of frequency bands and number of antennas), which is the detailed optimization of the antenna design. That is, tactical evolution, while the millimeter-band antenna design is a qualitative leap for mobile phone antennas (eg, array design and beamforming), which is a new orientation for antenna design. Strategic (revolution). Therefore, the technical and sophistication of mobile phone millimeter wave antenna design is predictably higher than current and 5G sub-6 GHz antenna design.
Dr. Huang also shared: “vivo actively laid out related patents and published international academic articles on millimeter wave antenna technology to more fully and more earnestly welcome the coming 5G era, and successfully completed the design and volume at this time. After measuring the performance of the 5G millimeter wave antenna of a mobile phone, there will soon be a new design and new results for the next round of mobile 5G millimeter wave so that the persistence and cultivation of vivo in the millimeter wave of mobile phones can help the user's wireless experience in the future. With contributions'.
In the end, Vivo Electronics Development Vice President Wang Xiaojun said: 'Technology is the spirit and direction of the vivo brand, and 5G is a new stage for mobile communication technology. The design of millimeter-wave antenna is the top priority for the hardware development of 5G mobile phones. Therefore, the millimeter wave antenna Design for the vivo is a key technology highland that must lead and innovate, in order to create continuous surprises for consumers.
