Abstract
A hearing aid, in particular an in-the-ear hearing aid, includes a device housing having a housing shell insertable into an auditory canal and a housing front plate closing the housing shell. A battery is accommodated in the device housing. A signal processing device having a ground plane is disposed at least in sections between the battery and the housing front plate. An antenna device, having at least two folded antenna arms, is disposed between the ground plane and the housing front plate. The antenna arms extend as three-dimensional spirals or helices along a height direction perpendicular to the ground plane, and have at least one turn or pitch. The antenna arms are electrically connected to one another by antenna poles spaced apart from the ground plane.
