1. We have proposed several glass-integrated antennas, such as a triple-band glass-integrated grid antenna, UWB MIMO metal mesh antenna and optical transparent MIMO antenna, the benefits and feasibility of embedding antennas in building structures made of glass are assessed by simulation and measurement. 2. We propose the concept of wireless friendliness of building material, and take the spatially averaged capacity as an evaluation metric of wireless friendliness that can be used to determine the optimised permittivity and thickness of glass. 3. We have modelled the radiation efficiency, gain and input impedance of the glass integrated antenna varying with glass permittivity and thickness, and several protypes of glass integrated antenna are fabricated. 4. We have proposed a set of machine-learning based optimisation method which can model and optimise glass integrated antenna efficiently to obtain desirable wireless, optical and thermal properties of glass.
Overview of the results:
During the work, we propose the first investigation on the impact of glass integrated with antenna arrays on the performance of indoor MIMO communications. We propose wireless friendliness as a new property that can be used to assess the wireless performance of building materials and to guide the design of a wireless friendly building; we propose a transparent ultrawideband (UWB) multiple-input multiple-output (MIMO) antenna based on wired metal mesh (MM) structure, compared to the current transparent MIMO antennas it has relative wider bandwidth, higher efficiency, higher gains, lower coupling and comparable transparency; we proposed an indium tin oxide (ITO) based transparent antennas for ultra-wide band and MIMO applications, the impacts of ingredient ratios and structures of glass on the wireless performance of antenna are investigated and optimised; we propose a multi-fidelity surrogate based optimisation method which can be used in efficient optimisation of antenna integrated in complex environment.
