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.
