Synthesis of an array antenna for hyperthermia applications

In the present work the synthesis of an array antenna for hyperthermia trea tment is developed. The selected antenna is an array antenna surrounded by a semicircular reflector which has shown to ease the penetration and focali zation in malignant biological tissues. A bolus is introduced as a protecti on in order to avoid an increasing heat hazard of superficial healthy tissu es. The electric held within the biological medium will be modeled by means of the well known method of moments. The electromagnetic coupling problem is expressed in a closed form, enabling both a synthesis and an optimizatio n procedure to be performed. Numerical results are included, illustrating t he capabilities of the array antenna.
