Method of antenna isolation with the help of periodic structures



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 ...

Mathematic modeling of the antenna array composed of microstrip radiators above an impedance surface of a generalized cylinder



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 ...

Current synthesis on open surfaces using the given directional diagram



The problem of finding: distribution of current density on an open surface, satisfying the Meixner condition in its contour, using the given directional diagram is solved. The current is found as a series that converges to L2(s) surface norm. The conditions of realizability of the diagram are examined, and methods of ...
