Dual-band metamaterial microwave absorber using ring and circular patch with slits

This paper proposes a dual-band metamaterial microwave absorber operating at 2.5 GHz and 5.8 GHz. The absorber consists of a ring and a circular patch with slits resonator structures printed on an FR4 dielectric substrate backed by a ground layer. The main advantage of the absorber lies in its desig...
