Design and Experiments of a Wideband mmWave Reconfigurable Intelligent Surface

In this talk, a 1-bit, dual polarized, wideband reconfigurable intelligent surface (RIS) is presented. The design constraints are discussed and details of the unit-cell are shown to understand its principle of operation. The PCB construction will also be presented, highlighting the challenges of building a mmWave RIS. Experimental results demonstrated a good agreement with the expected performance of the RIS, which will later be tested on the field as part of the 6G Sandbox Consortium. This presentation will cover the entire engineering life-cycle of the design of a mmWave RIS, from initial design, optimizing the bandwidth, PCB design and experimental setups used for our initial validation.
