1. An operating method of a deep body spread hyperthermia device, the operating method comprising:
generating a control signal to control patches attached to the skin of a user;
dividing the control signal into a first signal and a second signal having a phase different from a phase of the first signal;
transmitting the first signal and the second signal respectively to patches attached to opposing directions based on a body of a user, among the patches;
producing hyperthermia in a body of the user by radiating radio waves based on the first signal or the second signal received by each of the patches; and
shifting a phase of the first signal and a phase of the second signal to increase a phase difference between the first signal and the second signal over time,
wherein the transmitting comprises transmitting the phase-shifted first signal and the phase-shifted second signal to patches attached to different positions, among the patches.
