Abstract: Provided is a device for microwave hyperthermia that may attach a flexible patch on the skin of a user based on a cross-section of a body tissue of the user, for example, a joint and muscle of a leg and an arm and may emit microwaves towards a plurality of points of the body tissue through the patch. The microwaves emitted toward the body tissue may have the same phase and maximum power. Accordingly, a maximum heat generation point may be generated in an area adjacent to the plurality of points. The device for microwave hyperthermia may move the maximum heat generation point by sequentially changing a phase and a direction of each of the microwaves. The device for microwave hyperthermia may uniformly distribute and maintain heat for treating pain and/or infection over the entire cross-section or a partial area. The device for microwave hyperthermia may be portable.
