ABOUT THE REAL POSSIBILITIES OF MODERN COMPUTING SYSTEMS FOR DISTRIBUTED MULTIPLICATION OF LARGE-DIMENSIONAL MATRICES
The classical half-wave dipole has a rather small operating frequency band. The paper presents acomprehensive method for extending the frequency band of a dipole radiator. The broadband matchingeffect is provided based on the principle of private compensation of complex load. As the basis of thematching device, a matching method using a reactive loop is used, which has a good matching qualitywith a complex load with minimal geometric dimensions. A feature of the method is the consideration ofthe issue of matching a single design "matching device – Radiator-reflector". For this, it is necessary totake into account the influence of both the structural elements of the transmission line matching and the mutualreaction of the reflector and the symmetrical dipole. The Purpose of the work is to synthesize the designof a symmetrical dipole radiator with a matching reactive loop. The paper presents a design containing adipole excited from a two-wire line (which is also its struts), shorted at the end. This two-wire line is connectedin the middle part to the coaxial supply line. The reflector has a complex shape in order to provide thenecessary distance from the dipole to the reflector. For this purpose, the design of the dipole radiator hasbeen formatted, the number, nomenclature and range of variable parameters have been determined, and amathematical model has been formulated and verified. Based on this model, numerical studies of the designalignment level in a range of variable parameters have been carried out. Using a mathematical model, thepossibility of broadband matching is demonstrated, and the parameters of the primary model forelectrodynamic modeling are found. Based on the formed primary model, a computational experiment wasconducted using 3D electromagnetic simulation (HFSS) software in order to determine the optimal geometryand dimensions of the radiator structure. In one case, the maximum value of the operating frequency bandwas chosen as the criterion of optimality, in the other - the maximum directional coefficient. These casesreflect the practical tasks of using emitters of this type. The possibility of matching in a frequency band of atleast 80% has been demonstrated. The results of verification of the mathematical model, mathematical andelectrodynamic modeling, as well as the layout of the radiator are presented
