Abstract

The use of microwave radiation for biomedical purposes has been increasing in recent years. Among the most important applications are localized hyperthermia, noninvasive diagnosis and monitoring of cardiovascular system parameters and characterization of biological tissues. For all these purposes the design of suitable electromagnetic (e.m.) energy couplers is of fundamental importance. In this paper a new structure is suggested and assessed for a direct contact microwave applicator. The proposed radiating system is obtained using the microstrip transmission lines technique and its principal characteristics are very small sizes and weight, together with good matching and sufficiently defined and small irradiated value.
