COMPOSITE MAGNETIC SHEET AND MAGNETO-DIELECTRIC ANTENNA USING THEREOF

摘要

The present invention relates to a composite magnetic sheet and a magnetic antenna using the same, wherein the composite magnetic sheet according to the present invention is in contact with an antiferromagnetic layer and a ferrimagnetic layer, and includes a pattern at a bonding interface between the antiferromagnetic layer and the ferrimagnetic layer, Through this, the resonance frequency is increased due to the increase in the coercive force due to the exchange bias at these interfaces, so that high permeability and low permeability loss characteristics can be satisfied simultaneously in the GHz region.
