Active Admittance and Impedance of Hexagonally Sampled Dipole and Slot Connected Arrays

Analytical formulations of the active admittance and impedance of connected arrays based on dipole and slot antennas, respectively, when elements are arranged in a hexagonal lattice, are presented. Different canonical dielectric layers stratifications are considered. The formulations is based on multi-layer Green’s function spectral...

Ultrawide-Band Properties of Long Slot Arrays

In this paper the ultrawide-band properties of a long slot array are described. The study provides the rigorously derived Green’s function (GF) for an infinite long slot array. FromtheseGF active impedances and radiation patterns for various cases were obtained. The ultrawide bandwidths and the array performances of such apertures are...
