The infinite array of stepped plane-parallel waveguides with dielectric inserts and projected dielectric elements, excited by TEM-waves is analyzed in this article using the integral equation for electric field (polarization current) in the projected element and field linking method in the horn; the differential equation is solved using the Galerkin method using vector waves of the corresponding resonator as basis and weight functions; numerical results characterizing the suggested algorithm and...

It is obtained a new way to solve the problem of calculating radiation of horn antenna arrays, which is based on using the immersion method; the system of horns is considered a transition layer, coordinating the waveguides with the empty space and characterized by the matrix transparency coefficient. When deriving the immersion ...

On the basis of the asymptotic theory of diffraction, under the condition of slowness of change in the curvature radii, the mathematical theory of broadband conformal antenna array has been constructed. As an illustration of the operation of this model, the characteristics of the radiator located on an elliptical impedance surface are presented. When antenna systems are located on objects with curved surfaces, there ...
