The numerical research results of scattering characteristics of a microstrip–stubs reflectarrays, which have obtained due to a mathematical model, developed by the authors, are represented. The mathematical model of a reflectarray allows introducing into a construction of each microstrip element some shunts with ...

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 ...
