Abstract
Antenna carriers with magneto-dielectric material and beam-shaping elements for enhanced performance and radiation safety of electronic devices are described. One electronic device includes a housing, an antenna element disposed on an antenna carrier, and a printed circuit board (PCB) disposed within the housing, the printed circuit board including radio frequency (RF) circuitry. The antenna carrier can be made up of a plastic cap, a ground plane, and a magneto-dielectric substrate with both dielectric and magnetic properties. The plastic cap is disposed at a first side of the housing and the magneto-dielectric substrate is disposed on a top surface of the plastic cap. The antenna element is disposed on a bottom surface of the magneto-dielectric substrate and electrically coupled to the RF circuitry. The antenna element radiates electromagnetic energy in a resonant mode and the magnetic property of the magneto-dielectric material increase efficiency, frequency bandwidth, or both.
