An Epsilon Negative Metamaterial for Dual Band Operation in Microwave Range

A modified rectangular shaped epsilon negative (ENG) metamaterial (MTM) has been presented in this work. This metamaterial shows dual-band operation with epsilon negative (ENG) property. The unit cell is a combination of L and C-shape structure connected by copper link. The rectangular shape MTM design consists of FR-4 substrate material. Computer simulation technology (CST) software has been employed to execute the unit cell design, simulation and performance analysis. The metamaterial reveals transmission resonance at 2.47 GHz and 4.3051 GHz, which can operate S and C band of microwave range, respectively. Therefore, this composite material can be effectively utilized in antenna for microwave communication, permittivity sensing, long-distance radio telecommunication and other applications in the S-and Cbands.
