An Oval-Square Shaped Split Ring Resonator Based Left-Handed Metamaterial for Satellite Communications and Radar Applications

Abstract

Development of satellite and radar applications has been continuously studied to reach the demand in the recent communication technology. In this study, a new oval-square-shaped split-ring resonator with left-handed metamaterial properties was developed for C-band and X-band applications. The proposed metamaterial was fabricated on 9 × 9 × 0.508 mm3 size of Rogers RO4003C substrate. The proposed metamaterial structure was designed and simulated using Computer Simulation Technique (CST) Microwave Studio with the frequency ranging between 0 to 12 GHz. The simulated result of the proposed design indicated dual resonance frequency at 5.52 GHz (C-band) and 8.81 GHz (X-band). Meanwhile, the experimental result of the proposed design demonstrated dual resonance frequency at 5.53 GHz (C-band) and 8.31 GHz (X-band). Therefore, with a slight difference in the dual resonance frequency, the simulated result corresponded to the experimental result. Additionally, the proposed design exhibited the ideal properties of electromagnetic which is left-handed metamaterial (LHM) behavior. Hence, the metamaterial structure is highly recommended for satellite and radar applications.

SRR inspired inversion symmetry-shaped left-handed metamaterial with a high effective medium ratio for ASR and WLAN applications

“…Furthermore, the ASR-based unit cell design manifested the third-highest EMR value of 12.78 [ 26 ]. The oval square-shaped metamaterial with a size of 9 mm by 9 mm achieved an EMR of 6.03 for satellite and radar applications [ 43 ]. Other studies [ 45 , 46 ] that focused on the S-band yielded EMR values of 12.5 and 5 according to their structure size of 10 × 10 mm 2 and 24 × 18 mm 2 , respectively.…”

“…Its S-band electromagnetic characteristics determined the design's compactness, and the 8 × 8 mm 2 structure was recommended for airport surveillance radar systems. In 2022, Idrus et al [ 43 ] developed an oval square-shaped metamaterial structure utilising Rogers RO4003C with a resonance frequency of 5.52 GHz and 8.8 GHz for satellite and radar communication applications, respectively. This design yielded an EMR of 6.03.…”

“…Metamaterials are frequently recognized as constructed material for novel wave phenomena as the field advances quickly across electromagnetics today. Numerous prospects can be presented to new study areas by optimizing the metamaterial, such as absorber [ 7 , 8 ], antenna [ 9 ], gain enhancement [ 10 ], microwave application device - Wi-Fi, GPS [ 11 , 12 ], super-resolution [ [13] , [14] , [15] ], cloaking [ 16 ], radar cross-section (RCS) [ 17 ], reduction of specific absorption rate (SAR) [ 18 ], sensor [ 19 ], filter [ 20 ], perfect tunneling [ 21 ], radar and satellite [ 22 , 23 ], information metamaterial [ 24 ], terahertz metamaterial [ 25 , 26 ]. It's important to design the ideal system in several application sectors to obtain improved functioning with greater unit miniaturization and data measuring capability.…”

“…In the year 2022, Ali et al [11] proposed a polarization insensitive absorber using metamaterial properties for c-and x-band applications. Additionally, Idrus IN et al [12] offer an Oval-Square Shaped Split Ring Resonator designed specifically for radar and satellite communication applications. A thin octagonal-shaped SRR was proposed by Abouelna-gaTG et al [13] in 2020 for enhancing the functionality of an antenna that operates in the X and Ku frequency bands.…”
