Abstract (en)

A hearing aid having an attachment member and an antenna extending into the attachment element is provided. The hearing aid comprises a hearing aid housing having a microphone, a signal processor and a wireless communications unit connected to the signal processor for wireless data communication. The wireless communications unit is interconnected with an antenna having a first pole element and a second pole element for emission and reception of an electromagnetic field. The attachment member is connectable to the hearing aid housing and at least a part of the first pole element extends via the attachment member, and a second pole element of the dipole antenna extends in the hearing aid housing. Also disclosed is a set of attachment members wherein a first antenna element extending in a first attachment member has a first antenna length and a second antenna element has a second antenna length, and wherein the absolute relative difference of the first antenna length and the second antenna length is less than a first threshold, such as 10 %.
