Abstract The method of resolving synthesis tasks of ultrasonic antennas with restricted reactivity is considered. It has been proposed to estimate measure of ultrasonic antennas reactivity using function of local quality factor and integral estimation of local quality factor. Such way of getting estimations makes it possible to optimize geometry of emitting areas on antennas’ surfaces taking into account restrictions of reactivity and accuracy of implementing given radiation patterns. Introduced definitions of antennas energy effectiveness are more sensitive and make it possible to purposefully set locations of emitting areas during resolving tasks of synthesis with restricted reactivity without using variation methods.
