Abstract
An antenna configured in a hybrid circuit provides a compact design for a hearing aid to communicate wirelessly with a system external to the hearing aid. In an embodiment, an antenna includes metallic traces in a hybrid circuit that is configured for use in a hearing aid. The antenna includes contacts in the hybrid circuit to couple the metallic traces to electronic devices in the hybrid circuit. In an embodiment, the metallic traces form a planar coil design having a number of turns of the coil in a substrate in the hybrid circuit. In another embodiment, the metallic traces are included in a flex circuit on a substrate in the hybrid circuit. An antenna configured in a hybrid circuit allows for use in a completely-in-the-canal hearing aid.
