Mathematical model of dual-pass conical spiral antenna with finite size thin wire reflector

Article is devoted to the construction of a mathematical model dual-pass conical spiral antenna located on a flat rectangular reflector up Fine. Model building is carried out on the basis of integral representations of electromagnetic field coupling surface currents on the radiating electromagnetic field at any point in space. The question of the influence of the size and density of the reflector grid on its antenna pattern. Shows the results of numerical simulations.
