MTT-S Webinar | Microwave Lens Antennas by Prof Zhi Ning Chen, National University of Singapore


The rapid development of wireless technology has greatly increased the applications of multibeam antenna technology. 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 usage of lens antenna avoids the blockage by feeds. Furthermore the all high-gain beams generated by a lens antenna share the same aperture while the multibeam antenna arrays occupy much large aperture with lossy feeding structures. Conventional lenses are fully constructed by bulky dielectric. The flat, lightweight and PCB-based metasurface lenses have been developed for multibeam antennas.

This talk will introduce the concepts of metasurfaces and the technology of metasurface-based lenses at microwave bands. It will describe the recent progress in the research and development of microwave metasurface lens antennas with designs examples. Last, some of the multibeam lens antennas developed published and applied in 5G wireless network by our group from National University of Singapore will be introduced.
