Optimum scattering from an array of half-wave dipoles

On the Optimum Directivity of Uniformly Spaced Broadside Arrays of Parallel Half-Wave Dipoles (RESEARCH NOTES)

The nominal directivity for uniformly spaced broadside parallel half-wave dipoles associated with a uniform excitation is evaluated. The amplitude distribution for an optimized directivity is then obtained for different numbers of elements with the separations between the dipoles as a variable. The optimum and nominal directivities are compared for different spacings of the elements. While thes...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Optimum Array Processing and Representation of Nonstationary Random Scattering

'ins purpose of this paper is to extend scattering function concepts to nonstationary and correlated scattering and use appropriate extensions to study optimum array processors in inhomogeneous Gaussian random noise fields. For this end we will review common functional representations of nonstationary stochastic processes and indicate how these functional representations can be used for analysi...

Oblique Incidence Plane Wave Scattering from an Array of Circular Dielectric Cylinders

Abstract—A rigorous semi-analytical solution is presented for electromagnetic scattering from an array of circular cylinders due to an obliquely incident plane wave. The cylinders are illuminated by either TMz or TEz incident plane wave. The solution is based on the application of the boundary conditions on the surface of each cylinder in terms of the local coordinate system of each individual ...
