A new applicator using a multi-microstrip antenna for hyperthermia is proposed and developed. The applicator consists of semi-cylindrical microstrip elements which serve as non-invasive heating and temperature estimation inside the body. Major advantage of the applicator is that heating and temperature estimation are achieved through only simple switching; The array applicator can heat deep region with surface cooling. Meanwhile the applicator detects an appreciable change in the transmission coefficient of electric field.
