Multifunctional hybrid module and portable device comprising same
First Claim
1. A multifunctional integrated module, comprising:
- an antenna unit including heterogeneous antennas; and
a magnetic field shielding unit, disposed on one surface of the antenna unit, including a magnetic field shielding layer which includes shredded Fe-based alloy fragments and a dielectric filling at least a part of gaps between at least a part of some adjacent ones of the shredded Fe-based alloy fragments, configured to improve characteristics of the antennas and condense a magnetic flux toward the antennas;
wherein the heterogeneous antennas have different operating frequency bands from each other or perform different functions from each other,wherein the heterogeneous antennas include at least two types of antennas among a near field communication (NFC) antenna, a magnetic security transmission (MST) antenna, and a wireless power transmission (WPT) antenna,wherein a number of Fe-based alloy fragments of which diameters are less than 500 μ
m accounts for 40% or more of a total number of the Fe-based alloy fragments,wherein a number of Fe-based alloy fragments of which diameters are less than 50 μ
m accounts for 50% or less of the total number of the Fe-based alloy fragments.

Abstract
A multifunctional integrated module is provided. The multifunctional integrated module includes an antenna unit including heterogeneous antennas and a magnetic field shielding unit, disposed on one surface of the antenna unit, including a magnetic field shielding layer which includes shredded Fe-based alloy fragments and a dielectric filling at least a part of gaps between at least a part of some adjacent ones of the shredded Fe-based alloy fragments, to improve the characteristics of the antennas and condense a magnetic flux toward the antennas. According to this, although the functions are performed simultaneously, the respective functions are excellently expressed at the same time, and the durability can be ensured by preventing the deterioration of the function even with external physical shocks during use.
