5G Antenna Application Analysis

5G Antenna Application Analysis

Jan 14, 2022
There are two reasons for the growth of 5G antennas: the increase in the penetration rate of 5G antennas in mobile phones and the increase in the number of antennas brought about by the increase in 5G frequency bands, corresponding to terminal antennas and base station antennas respectively. According to the forecast of Bcc research, the global antenna market size will be 22.5 billion US dollars in 2021, and the smart antenna market size will be 7.6 billion US dollars; and according to Yole Development's forecast, the terminal antenna market space will increase from 2.23 billion US dollars in 2018 to 2022. 3.08 billion US dollars, the compound growth rate reached 8.4%.

The update of 5G antenna materials comes from the innovation and upgrading of 5G antenna technology. From 2G to 5G, 5G antennas have continued to be lightweight, miniaturized, multi-band, and high-frequency. 5G antennas are mainly divided into base station antennas and terminal antennas. In terms of base station antennas, in order to improve data transmission speed, slow down transmission delay, and increase mobility, 5G uses Massive MIMO (massive antenna) technology to increase the antenna from 4/8 channels to 64 channels and 128 channels, and at the same time, the operating power consumption of the device is also improved. The original device materials have been difficult to meet the needs of 5G, thus promoting the innovation of materials.

The application of 5G antennas includes the base station side and the terminal side. Whether in the base station or the terminal, the antenna is the middleware for signal transmission and reception. The quality of the antenna performance directly affects the quality of communication. The mobile phone terminal antenna is used to send and receive radio waves, and is connected to the RF front-end. It is the starting point of the receiving channel and the end point of the transmitting channel. The 5g base station antenna is similar to the terminal antenna and is also a signal converter, but the base station antenna connects the base station equipment and the end user.
