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 controllable loads. It is shown, that due to shunts it is possible to control amplitude and phase of a scattering fields.

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.

The algorithm of estimating the density of surface magnetic current induced on the array aperture has been obtained as a result of the rigorous solution of the problem of plane wave diffraction on a double periodic array of stripline elements of any shape with passive loads.

A short digest of the methods that are applied for antennae decoupling decreasing in the presence of an underlying surface is given. The computation results of weakly directional antennae decoupling with the help of periodic ribbed and strip structures located on an underlying surface along a coupling line for antennae are prezented; recommendations for the optimal (in a frequency range) construction of a deconpling structure are formulated. In this case some experimental data that confirm the possibility of the guarantee of a sufficiently high deconpling level by means of periodical structures are presented.
