Loop resonator apparatus and methods for enhanced field control
First Claim
1. An antenna for use in a mobile radio device, the antenna comprising:
- a ground plane; and
at least one resonator element disposed on said ground plane of said antenna, said at least one resonator element comprising at least a capacitance and an inductance and configured to form a resonance at a first frequency;
wherein said at least one resonator element is disposed on said ground plane at a selected first location proximate a location of maximum magnetic intensity so as to reduce electric field strength at a second location.

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.
