Abstract

In this paper, we present the analysis of an infinite array of printed dipoles covered by a unidirectionally conducting screen (DCS). This geometry is an idealization for a practical dipole array loaded on top by a strip-grating layer, which is of particular interest for low cross-polar radiation. The idealization using the UCS layer allows significant simplification in the analytical formulation, numerical computation, as well as basic physical understanding. Quite accurate results are obtained from the ideal model, valid for real grating-loaded dipole arrays with practical ranges of design parameters. The results from the present analysis are compared and contrasted with those from a rigorous analysis of the grating-loaded array, which demonstrates the practical usefulness and validity of the idealization.
