Hearing aid with adaptive antenna system
First Claim
1. A hearing aid comprising:
- a signal processor for processing one or more audio signals to compensate a hearing loss of a user of the hearing aid;
a wireless communications unit connected to the signal processor for wireless data communication; and
an antenna system with a data terminal and at least one control terminal, wherein the data terminal is connected to the wireless communications unit, the antenna system comprising a first antenna and one or more antenna feeds including a first antenna feed;
wherein the antenna system further comprises an antenna configurator for configuring the antenna system to operate in a selected antenna mode selected from a plurality of antenna modes including a first antenna mode and a second antenna mode according to a control signal transmitted on the at least one control terminal, wherein the antenna configurator is configured to apply a first antenna configuration to the data terminal when operating in the first antenna mode, and to apply a second antenna configuration to the data terminal when operating in the second antenna mode; and
wherein the first antenna configuration has a first polarization, and wherein the second antenna configuration has a second polarization different from the first polarization.
