METHOD, APPARATUS AND MATERIAL FOR RADIO FREQUENCY PASSIVES AND ANTENNAS

摘要

PROBLEM TO BE SOLVED: To avoid reduction in efficiency and bandwidth of radio frequency passive devices and antennas.SOLUTION: A package 10 has: a synthesized magnetic nanocomposite material 22 with aligned magnetic domains; a conductor 24 embedded within and extending through the nanocomposite material 22; antennas 20 constructed on the nanocomposite material 22; and contact pads 27 to connect to the conductor 24. The package is connected to a die 16 across a buildup layer (BUL) 12.
