Abstract (en)
[origin: WO2017153274A1] The invention relates to an antenna (18), in particular for a hearing aid (4), for wireless radio communication (20, 24), comprising a coil core (26) which extends along a longitudinal direction (34) and carries a number of windings (36), and comprising a planar first shield (38) that is located on an end face (30) of the coil core (26) and is made of a ferrimagnetic and/or ferromagnetic material. The first shield (38) extends at an angle to the longitudinal direction (34) of the coil core (26). The invention further relates to a method (84) for manufacturing an antenna (18) as well as to a hearing aid (4) comprising an antenna (18).
