Abstract
A radiating antenna element intended for portable radio devices and methods for designing manufacturing the same. In one embodiment, a loop resonator structure for enhanced field (e.g., electric field) is provided, the resonator having an inductive and a capacitive element forming a resonance in a first frequency band. The loop resonator structure is disposed substantially on the ground plane, thereby altering electrical energy distribution. The location of the resonant element is selected to reduce electric field strength proximate to one or more sensitive components, such as a mobile device earpiece, thereby improve hearing aid compliance. Capacitive tuning of the resonator, and the use of multiple resonator structures on the same device, are further described.
