A study of directive radiation from a horizontal electric dipole embedded in a grounded wire-medium slab covered with a partially reflecting surface in the form of a metal strip grating is presented. The combined effect of the volumetric metamaterial and the partially reflective surface allows for very directive beams. The performance is compared with antennas made from a wire medium slab alone and from an air substrate covered with a metal strip grating. In all cases omnidirectional beams are obtained.

Abstract
A study of directive radiation from a horizontal electric dipole embedded in a grounded wire-medium slab covered with a partially reflecting surface in the form of a metal strip grating is presented. The combined effect of the volumetric metamaterial and the partially reflective surface allows for very directive beams. The performance is compared with antennas made from a wire medium slab alone and from an air substrate covered with a metal strip grating. In all cases omnidirectional beams are obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
