| Abstract |
Background. The existing methods of creation of a directional pattern of cose-cant form for traditional types of antenna types do not ensure radiation and reception of Ultrawideband (UWB) signals. The problem of creation of antenna systems for UWB-signals is new. Use of microstrip printing antenna lattices is the most priority technology, capable of ensuring high recurrence of sizes, low cost, small metal consumption and mass. For microstrip UWB antenna lattices, using the signals of simple and complicated forms, at the present time there are no approved modes of shaping of a directional pattern of the set form as the classical methods of electrodynamics, developed for harmonious signals, are unacceptable for UWB-antennas.
Materials and methods. In the course of research the authors used the system approach, methods of classical electrodynamics, elements of the theory of opti-mization, antenna measurements of performances of emitters, numerical methods of solution of boundary problems of electrodynamics, full-scale tests and electrodynamic modelling via CST MICROWAVE STUDIO package, based on a finite-difference method in temporary area (FDTD). To calculate peak and phase distribution the researchers used MATLAB package as an instrument system.
Results. The authors developed a technique of synthesis of the structure of UWB linear printing antenna lattice with a directional pattern of the set form, actuating opti-mization of parameters of the individual emitter, being a part of antenna lattice, consid-ering values of parameters of analytical exposition and outcomes of calculating peak and phase weight coefficients of a directional pattern of the set form of a lattice, outcomes of the distribution of a field received by electrodynamic modelling on a surface of emitters of an antenna lattice using CST DESIGN STUDIO package,outcomes of calculation of admissible quantity of emitters and parameters of a microstrip power supply system of a lattice, electrodynamic modelling of parameters and performances of a linear printing antenna lattice as a whole, quantitative assessment of convergence of the received peak and phase distribution with the rated.
Conclusions. During full-scale experiments on mean squared deviation the authors estimated the convergence of a directional pattern form of a prototypeof UWB printing antenna lattice with outcomes of electrodynamic modelling.
