Use of the charge method for calculating parameters of a flat phased antenna array of printed radiators. The method of researching the electrodynamic characteristics of the PAA radiating curtain described in this work applies to antennas with rectangular printed radiators and also other radiators that can be presented as an array of rectangular items. However, the charge method is applied to researching a printed vibrator radiator (fig.1) being part of an antenna array in this particular example...

The mathematical model of longitudinal printed radiators phased antenna array is developed based on integral equations method of electrodynamics. Numerical results and measurements of broadband microstrip radiators of the phased antenna arrays characteristics are presented. The obtained results can be used at designing the flat phased antenna arrays containing longitudinal printed radiators. Antennas

Asymptotic solution for the diffraction problem on a periodic array of microstrip radiators located above the surface of an infinite generalized cylinder, the curvature radius of which satisfies the condition of slow change along the guide, is considered. By using the matrix reflectivity coefficients, the problem is solved assuming the multilayer isotropic dielectric coating is present. For partial excitation the electric Green tensor function of Maxwell equations is written in closed form, which...

Results of numeric modeling of impedance and polarizational characteristics of single-channel printed-circuit radiator having circular polarization in the base of the antenna array are presented. Possibilities for optimizing the characteristics in the frequency band and ...

A numerical algorithm for solving the problem of diffraction of electromagnetic waves on a multi-layer dielectric lossy sphere when amplitude-phase distribution of the exciting field is arbitrary is developed. The algorithm is based on representing the field on the source surface as an aggregate of the electrical and magnetic dipoles and reducting the vector problem to two scalar ones for the case of a point source. The results of calculating the directional diagrams and amplifying ratio are compared...

The problem of flat wave diffraction on a multi-layer meander polarizer is solved in a strict electrodynamic setting; to approximate the required electrical current a full orthogonal system of basis functions has been proposed; for the one- and four-layer polarizer cases the algorithm and program approbation has been executed. When considering the problem of transformation of electromagnetic field of the linear polarization within the field of elliptic polarization, and vice versa, the multi-layer...
