This application note presents the design of a compact 60 GHz patch antenna array with parasitic elements tailored for integration into Google Glass. The study compares configurations with and without parasitic elements, showing improved radiation patterns and elimination of nulls around 60° when parasitics are used. It also analyzes how mounting the antenna on Google Glass shifts the resonant frequency while preserving robust radiation performance, thanks to a full ground plane that isolates the antenna from the frame.
