Abstract: Disclosed are a deep body spread microwave hyperthermia device for personal uses and an operation method thereof. The operating method may include 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 to patches attached to different positions, among the patches, and 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.
