Ka-band Programmable Metasurface Demonstrations in Wireless Communication Scenarios

摘要

A programmable metasurface (PM) is a promising antenna array concept that can realize flexible electronically steerable beamforming. This property enables implementations of PM in wireless communication measurements. In this paper, by utilizing the steerable single beam and double beams generated from a PM at 28 GHz, communication systems regarding channel estimation, multipath single-input and single-output (SISO), as well as single-input and multiple-output (SIMO) systems are demonstrated and analyzed. The measurement results show system performances that prove the feasibility of PM wireless communication concepts.
