Title: Control the antenna beam behavior by customized metasurfaces

Abstract:
With modern wireless communications systems developing toward 5G and beyond, there is an increasing demand on the control of the antenna beam behavior, such as, high-gain pencil-beam radiation to expand the communication distance, and specific tilted-beam radiation to cover the required local service area. The conventional method to accomplish this task is to utilize antenna arrays in the types of parallel- or series-fed arrays. Nevertheless, since extra feeding network would inevitably increase the antenna design complicity, overall dimensions, and insertion losses. It is therefore highly desired to developed new antenna types and design methods to fulfill this task without relying on any complex feeding networks. In this talk, we will introduce several design methods to conveniently and efficiently control the beam behavior by customized metasurfaces.
