A 3D Electromagnetic Interference (EMI) suppression structure and an electronic device having the same, wherein a coplanar waveguide structure, an isolation layer, and a resonance layer may be installed. Furthermore, under the coplanar waveguide structure, the 3D EMI structure may be installed to connect to a conductor part of the resonance layer through a conductive connection part of the isolation layer, thereby further improving the EMI suppression effect and producing an excellent EMI suppression effect.
