Inverted f-shaped antenna for hearing instruments

Abstract

An antenna for a hearing instrument comprises an antenna element that is fed at an intermediate point between a first end of the antenna element and a second end of the antenna element. The antenna element has a J-shaped surface. The antenna also includes a ground plane element, a dielectric structure, and a shorting structure. The ground plane element that has a first segment and a second segment. A surface of the first segment has substantially the same shape as the J-shaped surface of the antenna element. The second segment connects a first end of the first segment to a second end of the first segment, thereby defining an opening through the ground plane element. The dielectric structure is disposed between the antenna element and the ground plane element. The shorting structure connects the first end of the antenna element to the ground plane element.
