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...

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...

Tags: antenna array , modeling , impedance , polarization Path: Home / Publications / Archives A numerical algorithm for solving the problem of diffraction of electromagnetic waves on a multilayer dielectric lossy sphere when amplitudephase 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...
