    CMC-Computers, Materials & Continua, Vol.71, No.2, pp. 2271-2284, 2022, DOI:10.32604/cmc.2022.021751

    Abstract In this paper, the design and performance analysis of an Inkjet-printed metamaterial loaded monopole antenna is presented for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The proposed metamaterial structure consists of two layers, one is rectangular tuning fork-shaped antenna, and another layer is an inkjet-printed metamaterial superstate. The metamaterial layer is designed using four split-ring resonators (SRR) with an H-shaped inner structure to achieve negative-index metamaterial properties. The metamaterial structure is fabricated on low-cost photo paper substrate material using a conductive ink-based inkjet printing technique, which achieved dual negative refractive index bands of 2.25–4.25… More >

    Bilateral Coupled Epsilon Negative Metamaterial for Dual Band Wireless Communications

    Md Mhedi Hasan1, Mohammad Tariqul Islam1,*, Md Moniruzzaman1, Mohd Hafiz Baharuddin1, Norsuzlin Binti Mohd Sahar2, Md Samsuzzaman3

    CMC-Computers, Materials & Continua, Vol.71, No.1, pp. 1263-1281, 2022, DOI:10.32604/cmc.2022.021388

    Abstract This work presents a dual band epsilon negative (ENG) metamaterial with a bilateral coupled split ring resonator (SRR) for use in C and X band wireless communication systems. The traditional split-ring resonator (SRR) has been amended with this engineered structure. The proposed metamaterial unit cell is realized on the 1.6 mm thick FR-4 printed media with a dimension of 10 × 10 mm2. The resonating patch built with a square split outer ring. Two interlinked inner rings are coupled vertically to the outer ring to extend its electrical length as well as to tune the resonance frequency. Numerical simulation is… More >
