Abstract
Left/Right (L/R) hearing assistance device (HA) symmetrical performance of the antenna is highly desired when using the same HA design for both the left and the right ears. Physical symmetry and loading of the antenna, both internal and external to the HA, is usually not possible because the antenna should avoid the microphone, battery, and switch locations within the HA. Described herein are antenna structures, hearing assistance devices with integrated antennas, and methods of wireless communication in hearing assistance devices which create symmetrical (L/R) antenna performance with physically asymmetrical antenna designs.
