Novel antenna tech allows multi-signal transmission for 6G networks

A breakthrough in antenna know-how that might revolutionize the way forward for wi-fi communications, notably for the upcoming sixth era (6G) networks, has been introduced by a analysis group led by Professor Chan Chi-hou, Chair Professor of the Division of Electrical Engineering at Metropolis College of Hong Kong (CityUHK).

The examine, “An artificial moving-envelope metasurface antenna for unbiased management of arbitrary harmonic orders,” was revealed in Nature Communications.

The group developed a novel metasurface antenna able to concurrently producing and controlling a number of frequency parts by way of software program. This main development guarantees to reinforce the effectivity and capabilities of wi-fi communication methods.

Conventional antennas are usually fastened of their capabilities. To reinforce antenna flexibility and management, the researchers proposed and experimentally demonstrated a novel antenna idea known as a “synthesis transferring envelope.” This know-how permits antennas to concurrently generate arbitrary harmonic frequencies and their wave properties to be managed by way of software program manipulation.

Notably, that is the first-ever reported antenna with such capabilities, marking a milestone in antenna design. The know-how has potential functions in next-generation large-capacity and high-security data methods, real-time imaging, and wi-fi energy switch.

The antenna can concurrently transmit a number of alerts to customers in several instructions, considerably rising channel capability. Furthermore, the combination of sensing and communications, essential for 6G wi-fi networks, is considerably superior by this innovation, which has far-reaching implications for future communication methods.

“The proposed synthesis method promotes the metasurfaces’ spectral controllability to a brand new stage,” defined Professor Chan, who can be Director of the State Key Laboratory of Terahertz and Millimeter Waves (SKLTMW).

“The unparalleled frequency controllability, along with its extremely easy coding technique (1-bit), sideband-proof, and potential for on-chip integration, supplies a proposed metasurface antenna that goes past present applied sciences, providing promising potential in wi-fi communications, cognitive radar, built-in photonics and quantum science,” stated Professor Wu Gengbo from the Division of Electrical Engineering and a member of the SKLTMW.

The analysis is a joint effort between CityUHK and Southeast College, Nanjing, China. Professor Wu and Dr. Dai Junyan, a former postdoctoral fellow at SKLTMW, are the co-first authors.
