1. An electronic device comprising:
a first electronic component;
a second electronic component; and
a printed circuit board (PCB) configured to connect the first electronic component and the second electronic component and block power noise in a target frequency band,
wherein the PCB comprises:
a first signal layer comprising a first signal plate, the first signal plate having a length pattern with a length corresponding to a first parameter of the target frequency band;
a first ground layer comprising a first ground plate, the first ground plate being positioned below the first signal plate and having a first area;
a second signal layer comprising a second signal plate positioned below the first ground plate;
a first dielectric positioned between the first ground plate and the second signal plate, the first dielectric having a first thickness and a first permittivity;
a second ground layer comprising a second ground plate, the second ground plate being positioned below the second signal plate and having a second area corresponding to a second parameter of the target frequency band; and
a second dielectric positioned between the second signal plate and the second ground plate, the second dielectric having a second thickness and a second permittivity corresponding to the second parameter.
