Abstract

See full text

An electrically small antenna operable in both single-ended and differential antenna systems, and corresponding circuitry configurations, is provided. The antenna may be arranged on or in a wearable audio device, such as an earbud. The antenna may include a first curved arm electrically coupled to a first port. The antenna may include a second curved arm of equal size and equal shape as the first curved arm and electrically coupled to a second port. The second curved arm may be rotationally positioned 180 degrees, relative to the first curved arm, about an imaginary axis perpendicular to a surface of the wearable audio device. The single-ended antenna system may include a radio frequency integrated circuit (“RFIC”), fixed matching network, a tuneable capacitor, and a switching circuit. The differential antenna system may include an RFIC, fixed matching network, a tuneable capacitor, and a balun.
