## 1 Introduction
Additionally, [PERSON] et al., developed a multi-band metamaterial absorber for radar application, with a focus on C- and X-bands [17]. Although the previous studies showed benefits for microwave frequency applications, they encountered problems in terms of size. The antenna size decreases with the increase in frequency. For the C-band frequency, the size of the antenna is larger compared to the X-band and Ku-band. Consequently, the size of the metamaterial structure will continue to be the primary concern in this study. The study of left-handed materials has been widely covered due to the unique properties that are useful for various applications. In 2017, [PERSON] et al., developed a dual band left-handed metamaterial by connecting a designed single-negative metamaterial to neighboring units with metallic wires [18]. A spherical spiral metamaterial unit cell that is smaller than \(\lambda_{0}\)60 was introduced by [PERSON] et al., in 2018 to produce negative permeability and negative permittivity [19]. Furthermore, in 2019, [PERSON] et al., designed a composite right-left hand (CRLH) metamaterial that produced a left-hand (LH) metamaterial at a frequency less than 6.8 GHz and a right-hand (RH) metamaterial at more than 6.8 GHz [20]. In the same year, [PERSON] et al., proposed a double-negative metamaterial by designing a novel two-dimensional (2D) metamaterial structure with a center symmetric T-shaped unit [21]. The structure operated at K- band and Ka-band frequencies. Additionally, [PERSON] et al., proposed a left-handed metamaterial absorber structure that is formed by the combination of an electrical resonator and a circular ring in 2020 [22]. The developed metamaterial absorber structure has a bandwidth of 4.66 GHz and resonance frequencies in the C-, X-, and Ku-bands. In 2021, [PERSON] et al., introduced an electrically tunable left-handed textile-based metamaterial that consisted of a decagonal-shaped split ring resonator and a slotted ground plane integrated with RF varactor diodes [23]. The metamaterial structure is designed by the researchers to gain a variety of advantages. The design idea is based on the trial-and-error method. The type of substrate, the size of the substrate, the thickness of the substrate, the width of the metal strip, the width of the split gap, the number of the split-ring resonator, the shape of the design structure, and others are the parameters that are important to produce a metamaterial design with good performance. The parameters can be adjusted to obtain the desired electromagnetic properties. There are various shapes of metamaterial design structures that have been introduced by researchers. In 2017, [PERSON] et al., designed double-sided spirals with a plate in the center of 64 mm \(\times\) 64 mm \(\times\) 0.8 mm unit cell metamaterials for wireless power transfer (WPT) system application [24]. They also demonstrated the effect of the adjustment in unit cell parameters, and it was proven that, by changing the parameters of the unit cell, there would be significant effects on resonance frequency. Additionally, in the same year, [PERSON] et al., proposed a H-shaped unit cell metamaterial for C- and X-band applications [25]. In 2018, [PERSON] et al., developed a dual band wide angle absorber consisting of three resonators, which were two cross double-arrow shaped ones, a ring resonator with four splits at the corner, and a square-ring resonator [26]. The proposed design was applicable for energy harvesting in GSM and ISM band applications. In 2019, [PERSON] and [PERSON] proposed a dual band symmetrically E-shaped split ring resonator with a peak absorption of 99% at 5.8 GHz and 92% at 7.8 GHz [27]. Additionally, [PERSON] et al., introduced a compact left-handed circular split ring resonator (CSRR) metamaterial structure for C- and Ku-band applications [28]. In 2020, [PERSON] et al., proposed a single-band split-ring resonator bounded cohesive symmetric hook C-shaped metamaterial for airport surveillance radar (ASR) system [29].
