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.

Biography:
Gabriel Gonçalves Machado obtained his BSc degree in Electronic Engineering from the Federal University of Pernambuco, Brazil. He has a PhD in Electronic Engineering with focus in the area of antennas and propagation, obtained from Queen’s University Belfast (QUB), UK. His PhD was related to thin FSS based microwave absorbers for applications in ‘busy’ antenna environments and the reduction of the radar cross-sections of metal backed antennas.
In 2021, he joined as a research fellow at the Centre for Wireless Innovation (CWI), part of Queen’s University Belfast, and his research has involved: virus and microwave interaction, GNSS antenna development, microwave absorbers, and his most recent focus is on the development of millimetre wave Reconfigurable Intelligent Surfaces (RIS) for 5G and 6G communications.
He joined Ulster University in August 2023, where he teaches Embedded Systems related modules. Beyond his interest in RIS development, he has a particular interest in the development of devices and practices in antennas and propagation focused towards sustainability, e-waste reduction, and energy efficiency.
