Glazing Unit Antenna RF Signal Reception

The patent applies multi-functionality by incorporating an antenna into the glazing unit structure, enabling it to perform both its primary function as an optical modulator and a secondary function as an RF signal receiver. The antenna is integrated into the substrate or pane structure, allowing the glazing unit to harvest energy from RF signals and enable wireless communication without requiring separate dedicated components, thus improving versatility while managing complexity through functional integration.

The patent implements self-service by enabling the glazing unit to harvest its own operating energy from ambient RF signals present in the environment. The antenna captures RF energy which is then rectified and stored to power the optical modulation function, allowing the system to be partially or fully self-powered without requiring external power connections. This reduces reliance on external power sources and enables autonomous operation where the harvested energy suffices for modulation tasks.

The patent applies nesting by integrating the antenna within the multi-layer structure of the glazing unit rather than placing it entirely on the exterior surface. The antenna is embedded between layers of glass, substrate, or coating materials, which provide physical protection from environmental factors such as weather, contamination, and mechanical damage. This nested arrangement allows the antenna to maintain its exterior positioning for optimal RF signal reception while being shielded by the protective layers of the glazing structure itself.
