- Abstract
- We have investigated the possibility of using the
2.45 GHz ISM band for communication between binaural
hearing aids. The small size of a modern hearing aid makes it
necessary to miniaturize the antennas to make this feasible.
Two different types of hearing aid placements have been
investigated: in the outer ear and in the ear canal. Both put
strict demands on the size of the antenna, which have been
miniaturized by applying disc loads and high permittivity materials.
The investigations have been done by FDTD simulation
of a modified SAM phantom head, where we have included a
simple model of the ear canal. Simulations show that the outer

The investigations have been done by FDTD simulation
of a modified SAM phantom head, where we have included a
simple model of the ear canal. Simulations show that the outer
ear placement is better, as it gives a total link loss of 48 dB.
The placement in the ear canal gives a total link loss of 92 dB. (Less)
