Abstract
A modal antenna is proposed that provides for dynamic tuning and optimization of antenna system parameters for SAR (Specific Absorption Rate) management in mobile wireless devices. A modular approach is described where the radiator and active components are integrated into a module, allowing the fixed radiator to be used across multiple wireless products and form factors. Multiple radiation modes can be generated by a single antenna structure with one or several of the modes designed to minimize SAR while maintaining efficient communication link performance. Proximity sensors or other sensors provide indicators to determine when mode selection is necessary.
