“…The designed MTM shows the beam steering properties, whereas no other references displayed the beam steering in the references. The exhibited bandwidth is 4.49 GHz, whereas only Hasan et al showed wide bandwidth compared with the designed one. The proposed MTM single unit cell is more compact with respect to other unit cells.…”

“…A 3D optical MTM had been constructed a prism to demonstrate negative refractive index at optical frequencies with a very high figure of merit of 3.5 and the negative index existing over a broad spectral range in Valentine et al Again, a chiral MTM had been printed on Rogers RT 5880 material, which showed resonance at C‐band and exhibited 5.14 GHz bandwidth from 4.0 to 9.14 GHz. Due to the bandwidth in the major portion of C‐band, the proposed chiral MTM was applicable for telecommunication applications . Further, a MTM design that enhanced nonlinear response with strong artificial magnetism, ensures a negative refractive index with bistable and self‐tunable response at 2011 .…”

The finite difference time domain method is applied for numerical modelling of composite dispersive material‐based proposed metamaterial, where the electromagnetic waves are propagating along the y‐axis with some exceptional properties in this paper. The existing frequency dispersive finite difference time domain method can be categorised into auxiliary differential equation method and the Z‐transform method, both of them are analysed in this paper. The auxiliary differential equation method has been introduced additional differential equations for describing frequency‐dependent material characteristics, and Z‐transform converts the frequency domain constitutive relations to Z‐domain relation. The proposed left‐handed metamaterial, single unit cell shows resonance at 5.48 GHz and the beam refraction characteristics by the incident beams on the structure. The incident beams are refracted 90°, 45° (positive refraction), and −25° (negative refraction) with respect to the metamaterial structure.

ABSTRAKPerkembangan lalu lintas dalam sistem komunikasi tanpa wayar telah menarik banyak pihak menumpukan perhatian kepada spektrum jalur lebar luas dalam gelombang frekuensi millimeter yang merupakan keperluan komunikasi generasi kelima (5G). Inspirasi antena yang boleh dikonfigurasi frekuensinya berasaskan metabahan dicadangkan untuk komunikasi 5G. Ia terdiri daripada garisan suapan lurus ekakutub dengan dua resonator cincin yang berpecah dua (DSRR). DSRR dibangunkan oleh resonator cincin berpecah luar dan dalam dengan jalur logam tembaga E-bentuk terbalik yang dihubungkan dengan resonator cincin luar. Teknik Integrasi Terhad berasaskan simulator elektromagnet CST Microwave Studio digunakan untuk reka bentuk dan kajian berangka. Pulangan Kerugian (S 11 ) menunjukkan resonan dalam 32.08 GHz, 35.07 GHz, dan 41.60 GHz. Prestasi antena yang boleh dikonfigurasi dicadangkan dianalisis dengan mengaktifkan atau menyahaktifkan DSRR. Walau bagaimanapun, metabahan yang direka menunjukkan ciri-ciri lengan kiri, padatan dalam ukuran dan lebih bersesuaian untuk aplikasi gelombang tanpa wayar 5G. Kata kunci: Aplikasi 5G; konfigurasi antena; metabahan lengan kiriABSTRACT Traffic development in the wireless communication system has attracted many parties concentrating on a broad bandwidth spectrum in the wave of frequency millimeters which is a fifth generation communication requirement (5G). Inspired antennae that can be configured by its own metamaterial is suggested for 5G communication. It consists of a straight feed line monopole with two resonator rings that split to two (DSRR). DSRR was developed by resonator the external split ring and in with the brass metal stripe of an overturned E-form linked to the resonator of the outer ring. Limited Integration techniques based on electromagnet CST Microwave Studio is used for numerical design and investigation. The Return of Loss (S 11 ) showed a resonant in 32.08 GHz, 35.07 GHz and 41.60 GHz. The antenna performance that can be configured is analyzed by activating or deactivating DSRR. However, metamaterial designed shows the characteristics of the left arm, a measure in measurements and is more appropriate for the 5G wireless wave application.

“…Therefore, due to these unique properties and for enhancing the performance of the antennas nowadays metamaterial antennas have become a research hotspot. Recently, a lots of dual- and triple-bands metamaterial (MMs) structure 1,2 with metamaterial antennas have discussed in research articles. Metamaterial antenna is a class for antenna inspired by metamaterial structure on radiating patch or ground plane for better performances.…”

A compact metamaterial inspired antenna operate at LTE, Bluetooth and WiMAX frequency band is introduced in this paper. For the lower band, the design utilizes an outer square metallic strip forcing the patch to radiate as an equivalent magnetic-current loop. For the upper band, another magnetic current loop is created by adding metamaterial structure near the feed line on the patch. The metamaterial inspired antenna dimension of 42 × 32 mm2 compatible to wireless devices. Finite integration technique based CST Microwave Studio simulator has been used to design and numerical investigation as well as lumped circuit model of the metamaterial antenna is explained with proper mathematical derivation. The achieved measured dual band operation of the conventional antenna are sequentially, 0.561~0.578 GHz, 2.346~2.906 GHz, and 2.91~3.49 GHz, whereas the metamaterial inspired antenna shows dual-band operation from 0.60~0.64 GHz, 2.67~3.40 GHz and 3.61~3.67 GHz, respectively. Therefore, the metamaterial antenna is applicable for LTE and WiMAX applications. Besides, the measured metamaterial antenna gains of 0.15~3.81 dBi and 3.47~3.75 dBi, respectively for the frequency band of 2.67~3.40 GHz and 3.61~3.67 GHz.
