Smart sensor device and antenna structure for use therewith

An antenna system for a smart sensor device, the antenna system comprising:

• a generally circular, substantially rigid substrate defining an aperture through a center thereof to permit light from above the substrate to reach below the substrate;
• a first radiative antenna element operating as a primary cellular antenna and integrated with the substrate so as to avoid the aperture;
• and
• a second radiative antenna element integrated with the substrate so as to avoid the aperture and arranged to receive location-based signals from one or more satellites of a satellite constellation system that provides geographic location information.
