  • Configuration of the antenna system 106 may comprise applying a first primary impedance to a first antenna feed of the antenna system and a second primary impedance to a second antenna feed of the antenna system, when the first antenna mode has been determined as the optimum antenna mode 104.
  • the configuration of the antenna system 106 may further comprise applying a first secondary impedance to the first antenna feed and a second secondary impedance to a second antenna feed of the antenna system, when the second antenna mode has been determined as the optimum antenna mode 104.
  • the determination of the optimum mode 104 may be performed by a signal processor.
  • the signal processor may be external to the antenna system, and the signal processor may transmit a control signal to the antenna system to configure the antenna system.
  • the signal processor may transmit the control signal to a control terminal of the antenna system.
  • the method 100 may be realized by the means of a hearing aid and an antenna system as described herein and in particular according to Figs. 1-6 and the accompanying descriptions.
