An efficient triband metamaterial absorber is presented for X- and K-band applications. The unit cell is of simple shape. The absorber is fabricated on a thin polyamide, which makes it flexible. The parameters of the designed absorber are optimized. The simulated results show that it has good absorption rate and polarization stability. The stability is exhibited over a wide range in both TE and TE modes of the incident waves. The measured results are on par with the simulated results. The measurement is carried out with the waveguide measurement method.

“…To achieve multiband operations for compact antennas, different techniques using planar technology have been investigated. Many methodologies were employed including different slot shapes [14,15,16], fractal ground [17,18,19,20], split ring resonators [21,22,23,24], shorting walls, and exploiting the fundamental and higher modes of the antenna [25]. A challenging issue for the wireless communications applications is the design and development of miniaturized multiband antennas [26].…”

A multiband planar antenna designed and proposed with resonator slots is presented. The proposed antenna consists of a planar hexagonal patch composed of two pairs of resonator slots. The antenna is designed using Isola FR408 substrate (ε r = 3.68 and tanδ = 0.0092) with a compact dimension of 21 × 28 × 1.6 mm 3 . The designed antenna has good impedance matching and radiation characteristics for the desired multiband frequencies. Multibands are obtained by etching two pairs of modified mirror-imaged L-shaped resonator slots on the hexagonal planar patch. Simulated and measured results of the antennas' reflection coefficient are provided and there is good agreement between the simulation and measurement results. The antennas' measured peak gains are between 2 dB and 5 dB and measured efficiencies are between 40% and 80%. The proposed antenna, when compared to other antennas, exhibits multiband characteristic by using a single-feed structure and generates different combinations of isolated lower frequency bands in miniature size. The antenna has stable directional radiation patterns and has the potential to meet the requirements of wireless communications applications.

“…Metamaterial merupakan suatu teknik yang membuat suatu struktur dapat menampilkan nilai permitivitas atau permeabiltasnya seolaholah bernilai negatif (Joshi et al, 2018) (Hindy et al, 2017) (G. et al, 2019). Selain itu, metamaterial juga dapat mengubah aliran arus pada antena sehingga antena memiliki frekuensi resonansi yang baru (Christydass & Gunavathi, 2018). Salah satu jenis metamaterial yang paling umum digunakan adalah Complimentary Split Ring Resonator (CSRR) (Priyanka & Shanmuganantham, 2018) (Raj et al, 2018) (Lu et al, 2017) (Thakur & Kunte, 2018).…”

Microstrip Patch Antenna works for Automatic Dependent Surveillance – Broadcast (ADS-B) and antenna frequency resonances at 1.09 GHz. Microstrip Patch Antenna dimension has big shape for antenna micostrip resonancing frequency at 1.09 GHz. In order to Solve this problem, metamaterial is chosen and Complimentary Split Ring Resonators (CSRRs) is the one of metamaterial technique. Complimentary Split Ring Resonators CSRRs is derived from a Split Ring Resonator (SRR) compliment. Early dimension of Microstrip antenna substrate and patch are calculated by Equation that dimension of substrate is 137x130 mm and dimension of patch is 85x65. Dimension of SRR that compliment forms to CSRRs is 9x6 mm for SRR inner ring and 13x10 mm for outer ring. Microstrip antenna VSWR is 1.134 and VSWR increases to 22,73 when CSRR is etched on antenna patch. In order to decrease antenna VSWR, optimation is applied by substrate and patch dimension iteration. Substrate and patch dimension Iteration is enlarge and reduce antenna substrate and patch width and length. Optimation result is VSWR that VSWR comes to 1,559 and substrate and patch dimension is reduced to 27,9% and 14,1%.
