Abstract :
[en] In the present work the synthesis of an array antenna for hyperthermia treatment is developed. The selected antenna is an array antenna surrounded by a semicircular reflector which has shown to ease the penetration and focalization in malignant biological tissues. A bolus is introduced as a protection in order to avoid an increasing heat hazard of superficial healthy tissues. The electric field 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 optimization procedure to be performed. Numerical results are included, illustrating the capabilities of the array antenna.
