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

We have investigated the possibility of using the

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)
