Detailed in a recently published paper, the researchers created a metasurface antenna that can generate and control multiple frequency components through software.
While traditional antennas tend to be fixed in their capabilities, the CityUHK-developed system can produce multiple frequencies at the same time, with their behaviour adjusted through software.

“The proposed synthesis approach promotes the metasurfaces’ spectral controllability to a new level,” stated Professor Chan Chi-hou, chair professor of the Department of Electrical Engineering at CityUHK, who led the research team.
Professor Wu Gengbo from the Department of Electrical Engineering and a member of the State Key Laboratory of Terahertz and Millimeter Waves (SKLTMW), said: “The unparalleled frequency controllability, together with its highly straightforward coding strategy (1-bit), sideband-proof, and potential for on-chip integration, provides a proposed metasurface antenna that goes beyond existing technologies, offering promising potential in wireless communications, cognitive radar, integrated photonics and quantum science.”
The project was a joint endeavour between CityUHK and Southeast University, Nanjing, China.
The research into next-gen antenna solutions was funded by grants from the Hong Kong Research Grants Council and the Shenzhen Natural Science Foundation Program.
