The principles of antenna arrays synthesis intended to be used as part of mobile radio engineering complexes are presented. Synthesis is performed at a given topology of the receiving-emitting structure with established relationships between the parameters of its structure and the efficiency indicators of signal radiation (reception) set on the basis of the requirements for radio engineering complexes. Its essence lies in the rational choice of parameters for the implementation of compromise technical solutions to achieve the required characteristics under the constraints established from the design and typical conditions of complexes application. The development of analytical methods for the synthesis of annular lattices has been carried out. When synthesizing radiation patterns of receiving-emitting structures with the levels controlled in specified directions and in order to reduce the amplification losses of the emitted (received) signals, the methods based on minimizing diagram functionals are shown to be most expedient. Efficient procedures to find extreme values of functionals are implemented using electrodynamic modeling packages (programs) such as CST MWS – Computer Simulation Technology Microwave Studio and Altair FEKO – FEldbe-rechnung bei Korpern mit be-liebiger Oberflache. The aim of the work is to substantiate the principles and to develop methods for the synthesis of antenna arrays in the interests of forming rational appearance of radio engineering complexes.
