Advanced 6G antenna on the way

A team of boffins from the City University of Hong Kong developed a special antenna that can control all five essential aspects of electromagnetic waves opening the way for future advanced systems.

According to Interesting Engineering the antenna, which they have named 'microwave universal metasurface antenna,' is capable of dynamically, simultaneously, independently, and precisely manipulating all the essential properties of electromagnetic waves through software control.

The antenna adjusts how strong the waves are, their timing, frequency, direction, and even the way they vibrate, all at the same time. It's the first time anyone has made an antenna that can do all these things simultaneously, marking a significant breakthrough in this field.

The antenna is great for handling and keeping a lot of data safe. It can transfer power wirelessly, charging devices without physical connections.

Another thing is that it can control the direction of its signals, adding an extra layer of privacy and security.

Although demonstrated in the microwave band, the UMA's concept can be expanded to terahertz frequencies using specific technologies, enabling applications in augmented reality, holography, integrated sensing and communications for 6G, quantum optics, and quantum information science, noted the researchers in their study.
