Performance-driven design and optimisation of millimetre-wave communication hardware

Building upon this foundation of optimised array design and recognising the increased sensitivity of mmWave signals to user-device interactions and blockages, the research extends to evaluating mmWave mobile handset performance through detailed simulations and extensive experiments. The impact of realistic user grips and orientations on handset antenna performance is measured, guiding the development of optimal antenna placement and beam steering strategies.

Additionally, this thesis investigates the practical integration of Reflective Intelligent Surfaces (RIS), demonstrating their potential to enhance mmWave signal propagation significantly. Both simulation-based and practical validations illustrate how RIS technology can effectively address line-of-sight and non-line-of-sight challenges, improving signal quality and system reliability. Overall, this investigation bridges existing gaps in mmWave hardware performance research, providing valuable insights and methodologies that support the practical deployment and advancement of future wireless communication systems.
