Synthesis of Plane Arrays with Restrictions in Fresnel Zone

Abstract

The approach that takes into account the requirements to the electromagnetic field (EM) characteristics in Fresnel zone while statement of synthesis problem according to prescribed amplitude pattern for the plane arrays is proposed. The synthesis problem is formulated in the variational statement. The optimizing functional contains the term, which provides the possibility to minimize the EM field amplitude in near zone of array. The respective Euler equation of functional is obtained and the successive approximation method is used for its numerical solving. The computational results are discussed.
