چکیده
The development and improvement of the dual-band 802.11ac standard Wi-Fi wide bandwidth satellite communication devices are currently research subjects that have garnered significant interest. In this paper, double C-shaped two split-ring resonator (SRR) bounded unit cells were developed, which applicable for S, C, X band applications, including applications its effective medium ratio (EMR) 15.6, results in a 2.4 GHz resonance frequency (S21 < −10 dB) 1650 MHz at an 11.5 frequency. A copper popular substrate material Rogers RT 5880 (thickness 1.575 mm) adopted analyzing characteristics cell. 8×8 mm2 structure was designed simulated using commercially available electromagnetic simulator CST (Computer Simulation Technology) Studio Suite 2019, utilized four frequencies: GHz, 5.6 8.93 GHz. electric field, magnetic surface current distribution examined by modifying metamaterial cell design structure, showing results. To confirm simulation results, newly double-negative (DNG) also with Ansys High-Frequency Structure Simulator (HFSS) compared extracted suggested is advised usage superior long-distance performance efficiency compactness structure.

Bilayer metamaterial: analysis of left-handed transmission and retrieval of effective medium parameters
We report an experimental and numerical analysis of a planar metamaterial designed for normal-to-plane propagation, and operating at microwave frequencies. The metamaterial consists of cutwire and wire patterns, which are arranged periodically on both sides of a dielectric layer, in the form of a bilayer. The left-handed transmission band of the metamaterial is demonstrated experimentally. The ...
