Usually antenna arrays or reflector antennas are the good candidates for multibeam design with complicated RF or digital systems. On the other hand\, the classic lens can be used to generate multiple beams naturally by locating the feeds at different positions behind the lens to form a multibeam lens antenna. Compared with reflector antennas\, the usag e of lens antenna avoids the blockage by feeds. Furthermore the all high-g ain beams generated by a lens antenna share the same aperture while the mu ltibeam antenna arrays occupy much large aperture with lossy feeding struc tures. Conventional lenses are fully constructed by bulky dielectric. The flat\, lightweight and PCB-based metasurface lenses have been developed fo r multibeam antennas. This talk will introduce the concepts of metasurface s and then the technology of metasurface-based lenses at microwave bands. After that\, the recent progress in the research and development of microw ave metasurface lens antennas is updated with designs examples. Last\, som e of the multibeam lens antennas developed published and applied in 5G wir eless network by our group from National University of Singapore will be i ntroduced.\n\nZhi Ning Chen received his BEng\, MEng\, and PhD degrees all in Electrical Engineering from the Institute of Communications Engineerin g (ICE)\, China and his second PhD degree from the University of Tsukuba\, Japan\, respectively.\n\nDuring 1988-1995\, he worked as a Lecturer and l ater a Professor at ICE as well as a Postdoctoral Fellow and later an Asso ciate Professor at Southeast University\, China.
