 5G and future antenna technology-1-C&T RF Antennas Inc




Abstract: According to the definition of the industry, an antenna is a transducer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa, ie transmitting or receiving. Electromagnetic waves. Popularly speaking, whether it is a base station or a mobile terminal, the antenna acts as a middleware for transmitting signals and receiving signals.

 

Over the past two decades, we have witnessed the shift in mobile communications from 1G to 4G LTE. During this period, the key technologies of communication are changing, and the amount of information processed has multiplied. The antenna is an indispensable component to achieve this leapfrog.

 

Now, the next-generation communication technology, 5G, has entered the end of the standard-setting stage, and major operators are actively deploying 5G equipment. Undoubtedly, 5G will bring a new experience to users, it has a transmission rate ten times faster than 4G, and puts new requirements on the antenna system. In 5G communication, the key to achieving high speed is millimeter wave and beamforming technology, but the traditional antenna obviously cannot meet this demand.

 

What kind of antenna is needed for 5G communication? This is a problem that engineering developers need to think about.

Evolution and trend of mobile communication base station antenna

The base station antenna is developed along with network communication, and engineers design different antennas according to network requirements. Therefore, in the past few generations of mobile communication technologies, antenna technology has also been evolving.

 

The first generation of mobile communication used almost all omnidirectional antennas. At that time, the number of users was small and the transmission rate was low. At this time, it was also an analog system.

By the second generation of mobile communication technology, we entered the cellular era. The antenna at this stage has gradually evolved into a directional antenna, and the general lobe width includes 60° and 90° and 120°. Taking 120° as an example, it has three sectors.
