Method apparatus and material for radio frequency passives and antennas

摘要

A method apparatus and material are described for radio frequency passives and antennas (20). In one example, an electronic component (such as a semiconductor package 10) has a synthesized magnetic nanocomposite material (22) with aligned magnetic domains, a conductor (20) embedded within or over the nanocomposite material, and contact pads (vias 24) extending through the nanocomposite material to connect to the conductor. The nanocomposite material retains the magnetic properties at higher frequencies with reasonable permittivity and permeability. An antenna area can be reduced with the nanocomposite material.
