Abstract

This paper presents omega-shaped resonant elements constructing a reflectarray for a carpet cloak. The dimension of a unit cell in the x and the y directions are dx = dy = 10.0 [mm] and the thickness of dielectric substrate with permittivity ϵr = 1.67 is h = 5.0 [mm]. We use 12 kinds of elements at the design frequency 10 GHz. To verify usefulness of the proposed elements, a carpet cloak constructed by them is designed and fabricated for experimental consideration. The scatterer has a triangular shape, and the horizontal width and the height are 240 [mm] and 35 [mm], respectively. The effectiveness is verified thorough evaluation of the calculated and the measured radiation patterns.
