Recently, China Mobile Research Institute and Southeast University Millimeter Wave National Key Laboratory have successfully developed a double circular polarized reflective array antenna based on hybrid phase reflection primitive technology.
In the context of "lens antenna" being widely used by the three major operators, what role will China Mobile's R&D achievement play in enterprises, industries and markets? Operator Finance Network will try to reveal the secret next.
According to public information, Longbo lens antenna has high radiation efficiency in the Sub-6GHz frequency band and wide vertical plane beam, which can meet the coverage needs of long-distance scenarios such as bridges; however, in the millimeter wave band, traditional lenses have problems of high dielectric loss, high profile and non-planarity, which greatly damages the coverage effect of 5G base station .
and China Mobile's dual circular polarized reflective array antenna research is conducted to reduce losses and improve caliber efficiency.
It is reported that Longbo lens antenna is not only compatible with 900MHz, 1800MHz and FA frequencies, realizing 4G and 5G multi-frequency fusion, but also supports 2.1GHz and 3.5GHz multi-frequency fusion and multi-frequency sharing, which is suitable for operators' 5G network construction.
In July this year, it was mentioned in an article titled "Strengthen the sea chart and contributing the strength of the maritime power to build a strong marine country" that when Hainan Unicom and Zhanjiang Unicom were carrying out network coverage work on the Qiongzhou Strait channel and sea surface, they used the high-gain lens antenna .
In a report conducted by a media last year, Changde Telecom used Longbo lens antenna to ensure smooth signal of mobile base stations in order to ensure the network coverage of the testing point of Changde First People's Hospital in Hunan Province.
Although it is impossible to find out which specific time point the three operators started to enable "lens antenna" in 5G signal coverage, judging from the existing data, the overall progress of Mobile, China Unicom and Telecom are still very close.
I just don’t know when the latest double-circle polarized reflective array antenna developed by China Mobile Research Institute will be actually applied to the construction work?
