Abstract
A wireless transmission system disclosed herein includes a radiating structure integrated into a computing device case that substantially encloses electronics of a computing device. The radiating structure includes an insulator that forms a boundary with the metal plate on the computing device case. A proximity sensor collects data from an exposure point located within the radiating structure.
