Microwave Antennas for Thermal Therapy

Abstract

Microwave energy is a heating source used for localized hyperthermia. Depending on the position and size of the target tumor,several types of antennas,which radiate microwave energy to the target, can be selected. This paper describes two ty pes of heating schemes which can be used with microwave energy, and provides brief explanations of the basic engineering involved. In addition, methods use for evaluations of antenna performance are described. Key
