Vivo And Qualcomm Cooperate Successfully To Develop 5g Millimeter Wave Antenna Array For Mobile Phones

The pace of 5G (fifth generation mobile communication) is getting closer and closer, and the new challenge to the design of mobile antenna is becoming more and more urgent and severe. Recently, vivo and Qualcomm announced that both sides have successfully developed a mobile 5G millimeter wave antenna array and integrated it into the vivo real machine, and complete the whole machine empty energy measurement.

Dr Huang Huanqu, an antenna technical director and chief antenna expert in charge of the vivo antenna pre research team, said: "vivo from WiGig (i.e. wireless Gigabit, IEEE 802.11ad) to 5G millimeter wave, and continuously research and Practice on the development of mobile millimeter wave antennas, which illustrates the importance of vivo to millimeter wave antenna technology and 5G technology. Successful development and production of a mobile phone 5G millimeter wave antenna array marks the vivo accumulation in the design of millimeter wave antenna technology and mobile phone industry leader, again forward step solid".

At present, the frequency of 3GPP for the millimeter wave band planned by 5G is from 24.25 GHz. For the users, it can reach high speed data transmission because of the high bandwidth caused by the high working frequency of the millimeter wave. It helps the 5G peak data transmission rate to reach 10~20 Gbps, that is, the 10~20 times the peak data transmission rate of the current 4G LTE, so for AR. VR, AI, and UHD (Ultra HD) image transmission applications have significantly better wireless experience. However, also because of millimeter wave high frequency, resulting in energy loss encountered in millimeter wave propagation and electromagnetic wave shielding effect, is now commonly used in mobile phone frequency increased dramatically. Therefore, in response to millimeter wave band, there should be different design concepts and schemes with the current mobile antenna, so as to achieve better wireless communication quality.

Dr. Huang Huanqu said: "for mobile antenna design, the sub-6 GHz from 1G to 5G is basically the increase of the quantity (such as the number of bands and the number of antennas), that is, the refinement of the antenna design, that is, the evolution of the tactical (tactical) (Evolution), and the antenna design of the millimeter wave band, for the mobile antenna, It is a qualitative leap (such as: design and array beam forming), is the new positioning of the antenna design, which is the strategic changes (strategical) (revolution). Therefore, the technical and delicate design of the millimeter wave antenna for mobile phones is obviously higher than that of today's 5G sub-6 GHz antenna design.

Dr. Huang Huanqu also shared: "vivo has actively distributed related patents and published international academic articles on the millimeter wave antenna technology to meet the upcoming 5G era more comprehensive and more rammed, and, after the successful completion of the design and measurement of the 5G millimeter wave antenna performance of the mobile phone, will soon have the next round of 5G millimeter wave. Design and new achievements to make vivo's persistence and Cultivation on mobile phone millimeter wave can help and contribute to the user's wireless experience in the future.
Finally, vivo Electronic Development Deputy Chief Wang said: "technology is the spirit and direction of the vivo brand, and 5G is the new stage of mobile communication technology. The design of the millimeter wave antenna is the top priority of the development of the hardware of the 5G cell phone, so the design of the millimeter wave antenna is the key technical highland for the vivo, which must be led and innovating. Continue to create surprises.
