Hearing aid and method for producing a hearing aid

1. A hearing aid, comprising:

a hearing aid housing;

an antenna device constructed to at least one of receive or transmit electromagnetic waves having a predetermined wavelength lambda;

said antenna device having a frame of non-conductive material incorporated in said hearing aid housing, said frame being constructed for holding assemblies of the hearing aid; and

said frame having an electrically conductive structure being an integral part of said frame.

2. The hearing aid according to claim 1 , wherein said electrically conductive structure is disposed on said frame to provide said antenna device with a reception characteristic being substantially symmetrical with respect to a first plane through said frame, said first plane being oriented parallel to a second plane being a plane of symmetry with respect to the head of a wearer, when the hearing aid is worn in accordance with its intended use.

3. The hearing aid according to claim 1 , wherein said electrically conductive structure has a first arm and a second arm being electrically interconnected at a base point, said first arm extends in a first direction and said second arm extends in a second direction from said base point, and said first direction and said second direction form a substantially right angle and said second arm is at least twice as long as said first arm.

4. The hearing aid according to claim 3 , which further comprises at least one of a transmitting or receiving device for coupling electric power in or out, said first arm having a coupling point disposed at an interval from said base point and coupled to said at least one of a transmitting or receiving device.

5. The hearing aid according to claim 4 , wherein said base point has a direct electrical connection to an electrical ground of said at least one of a transmitting or receiving device.

6. The hearing aid according to claim 3 , wherein said antenna device is disposed on said frame with said second direction being oriented substantially parallel to a second plane forming a plane of symmetry for the head of a wearer, when the hearing aid is worn in accordance with its intended use.

7. The hearing aid according to claim 2 , wherein said electrically conductive structure has a first arm and a second arm extending away from a coupling point, and at least one of a transmitting or receiving device is coupled to said coupling point for coupling electric power in or out.

8. The hearing aid according to claim 7 , wherein said first arm and said second arm extend substantially parallel to one another and substantially symmetrically with respect to the first plane.

9. The hearing aid according to claim 2 , wherein said electrically conductive structure forms a loop.

10. A method for producing a hearing aid, the method comprising the following steps:

providing a hearing aid housing;

providing an antenna device constructed to at least one of receive or transmit electromagnetic waves having a predetermined wavelength lambda;

providing the antenna device with a frame of non-conductive material, the frame being constructed for holding assemblies of the hearing aid;

patterning a surface of the frame;

applying an electrically conductive layer to the surface of the frame; and

incorporating the frame into the hearing aid housing.

11. The method according to claim 10 , which further comprises initially patterning the surface of the frame and then applying the conductive layer only in accordance with the patterning.

12. The method according to claim 10 , which further comprises initially applying the conductive layer to the surface of the frame and then patterning the conductive layer.
