Abstract
An ear-worn electronic device is configured to be worn by a wearer and comprises a housing configured to be supported by, at, in or on an ear of the wearer. Electronic circuitry is disposed in the housing and comprises a radio frequency transceiver and a power source. An antenna is disposed in, on, or extending from the housing and operably coupled to the transceiver. A non-Foster circuit is operably connected to the antenna and coupled to the power source. The non-Foster circuit is configured to actively load the antenna and provide a negative reactance that offsets a reactance of the antenna.
