Model researches of a single-mirror antenna with a dual-band log-periodic irradiator directional properties in MathCAD



The results of single-mirror antenna with a dual-band log-periodic irra­diator geometric parameters optimization and model researches of it’s range properties in MathCAD are presented in this article. The model of the mirror antenna radiation field used by the authors is based on the base of the surface currents method, the method of induced EMFs and theory of electric circuits with distributed parameters. The results of the research showed the adequacy of the constructed model and the compliance of the directional properties of the mirror antenna with the requirements imposed on them.
