An improved dual-band square-Z-shaped meta-atom is presented. It shows a bandwidth of 3.61 GHz, where the operating frequency ranges from 2.0 to 14.0 GHz. The meta-atom is split in such a way that it appears as a square-Z-shaped structure and is printed on an epoxy resin fibre substrate material. The dimensions of the single unit cell and array structure are respectively, 10 x 10 mm2 and 200 x 150 mm2. Also the unit cell and 1 x 2, 2 x 2 and 4 x 4 arrays are studied for double negative characteristics. CST Microwave Studio 3D-electromagnetic simulator is used to design and perform investigation. The performance of a meta-atom unit cell is measured by wave guide ports. The measured and simulated results matched well and are applicable for C- and X-band applications.

Abstract


An improved dual-band square-Z-shaped meta-atom is presented. It shows a bandwidth of 3.61 GHz, where the operating frequency ranges from 2.0 to 14.0 GHz. The meta-atom is split in such a way that it appears as a square-Z-shaped structure and is printed on an epoxy resin fibre substrate material. The dimensions of the single unit cell and array structure are respectively, 10 x 10 mm2 and 200 x 150 mm2. Also the unit cell and 1 x 2, 2 x 2 and 4 x 4 arrays are studied for double negative characteristics. CST Microwave Studio 3D-electromagnetic simulator is used to design and perform investigation. The performance of a meta-atom unit cell is measured by wave guide ports. The measured and simulated results matched well and are applicable for C- and X-band applications.
