In the past two decades, we have witnessed the transformation of mobile communications from 1G to 4G LTE (4G LTE Antenna). During this period, the key communication technology is changing, and the amount of information processed has doubled. The antenna is an indispensable component to achieve this leapfrog improvement.
According to the industry's definition, an antenna is a converter that transforms the guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa, that is, transmitting or receiving electromagnetic waves. In layman's terms, whether it is a base station or a mobile terminal, the cellular repeater antenna acts as a middleware for transmitting and receiving signals.
At present, the next-generation communication technology-5G (Cellular 5G Antenna) has entered the end of the standard formulation stage, and major operators are also actively deploying 5G (5G Antenna) equipment. Undoubtedly, 5G (5G Antenna) will bring a brand new experience to users. It has a transmission rate ten times faster than 4G (4G LTE Directional Antenna) and puts forward new requirements on the antenna system. In 5G (5G Antenna) communications, the key to achieving high rates is millimeter wave and beamforming technology, but traditional antennas obviously cannot meet this demand.
In the future, the antenna must be designed with the system instead of separately. It can even be said that the antenna will become a bottleneck of 5G (5G Antenna). If this bottleneck is not broken, the signal processing on the system will not be realized, so the antenna has become the key technology of 5G (5G Antenna) mobile communication system. The antenna is not just a radiator, since it has filtering characteristics, amplifying effect, and can suppress interference signals. It does not require energy to achieve gain, so the antenna is more than just a device.
