Antenna designs for hearing instruments

An antenna for an in-the-ear hearing instrument, wherein the antenna is connected to:

• a first feedline segment extending laterally along an inner lateral surface of a shell of the hearing instrument, and
• a second feedline segment extending laterally along the inner lateral surface of the shell of the hearing instrument, and
• wherein the antenna comprises:
• a first arm connected to the first feedline segment and initially extending in an inferior direction, along the inner lateral surface of the shell, from the first feedline segment;
• and
• a second arm connected to the second feedline segment and initially extending in a superior direction, along the inner lateral surface of the shell, from the second feedline segment,
• wherein the inner lateral surface is a first inner lateral surface of the shell, the first arm further includes a first lateral segment, an inferior segment, and a second lateral segment,
• the first lateral segment extends along the first inner lateral surface of the shell, the inferior segment of the first arm extends in a sagittal direction along an inner inferior surface of the shell, the second lateral segment of the first arm extends along a second inner lateral surface of the shell,
• the second arm comprises a lateral segment and a superior segment, wherein:
• the superior segment of the second arm extends along an inner superior surface of the shell toward a medial end of the shell, and
• the lateral segment of the second arm is connected to a lateral end of the second feedline segment and extends from the lateral end of the second feedline segment in a superior direction along an inner posterior surface of the shell and the inner superior surface of the shell, wherein a superior end of the lateral segment of the second arm connects to a lateral end of the superior segment of the second arm.
