Over the past two decades, we have witnessed a shift in mobile communications from 1G to 4G LTE. During this period, the key technologies of communications are changing, and the amount of information handled has multiplied. The antenna is an indispensable component to achieve this leap-forward promotion.
According to the definition of the industry, an antenna is an inverter that transforms a guided wave propagating on a transmission line into an electromagnetic wave that propagates in an unbounded medium (usually free space) or vice versa, that is, transmits or receives electromagnetic waves. It is popular to say that whether it is a base station or a mobile terminal, the antenna acts as a middleware for transmitting and receiving signals.
Now that the next-generation communications technology, 5G, has entered the end of the standard-setting stage, major carriers are also actively deploying 5G devices. Needless to say, 5G will bring new experiences to users. It has a transmission speed 10 times faster than 4G and puts forward new requirements for antenna systems. In 5G communication, the key to achieving high speeds is millimeter wave and beam forming technology, but traditional antennas obviously cannot meet this demand.
What kind of antenna is required for 5G communication? This is a problem that project developers need to think about. For this reason, Lei Fengwang IoT Technology Review invited the National University of Singapore tenured professor and IEEE Fellow Chen Zhining to explain the future antenna technology in 5G mobile communications.
In the future, the antenna must be designed together with the system rather than a separate design. It can even be said that the antenna will become a bottleneck for 5G. If this bottleneck is not broken, signal processing on the system cannot be realized, so the antenna has become a 5G mobile communication system. Key technologies. The antenna is more than just a radiator. It has filtering characteristics, amplification, and suppression of interference signals. It does not require energy to achieve gain, so the antenna is more than just a device.
