This paper presents an ultra-thin dual-band polarization-insensitive metamaterial absorber for C-band applications. The proposed structure comprises of a square loop and a modified split ring resonator on the top surface of a metal grounded dielectric substrate. The designed absorber offers low profile with a thickness of λ0/56 and λ0/49at 5.4 GHz and 6.1 GHz, respectively, where λ0 is free space...
In this paper, an ultra-wideband ring-shaped metamaterial antenna with modified phi-shaped split ring resonator has been proposed. The proposed antenna has a size of 35 mm × 37 mm × 1.6 mm and shows dual-band characteristics. The proposed metamaterial antenna has an impedance bandwidth of 14% (centered at 2.65 GHz) and 114.5% (centered at 7.25 GHz) for the first and second band respectively. Modified...
