Modelling and Analysis of Parasitic Metamaterial Loaded Inverted L‐Antenna With Various Substrate Materials for Sub‐6 GHz 5G, WLAN, WiMAX, and LTE bands (B42 and B43)

ABSTRACT An inverted L‐shaped dual band monopole antenna with a parasitic octagonal split ring resonator (OSRR) is proposed for multiple modern wireless communication systems. The proposed antenna is designed and evaluated with the help of CST Microwave Studio. The antenna is fabricated on an FR4 substrate with an overall footprint of 19 mm × 19.5 mm × 1.6 mm. The proposed antenna has two operating bands, which extends from 2.70 to 4.18 GHz and 4.92 to 5.20 GHz, supporting various wireless applications such as wireless local area network (WLAN), wireless interoperability for microwave access (WiMAX), long‐term evolution (LTE), and sub‐6 GHz new radio (NR) bands (n48/n77/n78/n79). The metamaterial characteristics are analyzed and validated with the NRW method of parameter extraction. Further, the implemented design is analyzed with various dielectric materials, including ARLON AD 250C, ARLON AD 300D, FR‐4, ROGER RO 3003, ROGER RO 3006, and ROGER TMM 10 to show the impact of substrate material on the characteristics of the proposed antenna. The prototype of the proposed antenna is fabricated and experimentally tested for validating the simulated outcomes. The measured results demonstrate strong agreement with the simulated results. Due to its compactness, the proposed antenna proves itself as a potential choice for the next generation wireless communication systems.
