Research of director radiators in convex cylindrical antenna array



Based on the asymptotic theory, characteristics of convex cylindrical antenna array consisting of director radiators are studied. To determine the distribution of currents of the radiator vibrators, the numeric projective method is used. Results of numeric computations ...

Mutual relation in convex cylindrical antenna arrays of arbitrary form composed of aperture radiators



Based on the asymptotic diffraction theory methods, the problem of determining the near field of the convex cylindrical antenna array composed of aperture radiators is reduced to the boundary value problem in the single cell of the array, which is solved using the ...

About the inaccuracy of measuring the directivity factor and directional diagrams of antennas at a short distance



The first three terms of the asymptotic decomposition of the transfer ration between two antennas with arbitrary directional diagrams and polarization types are obtained. The formulas for the distance that can be used to measure primary and lateral radiation with the given inaccuracy ...
