“…Metamaterial are integrated into the antenna by either arranging their unit cells in such a way that they surround the antenna radiating element [23,32], or using them as a ground plane loading or etching of the antenna, in which AMC functions as a zerodegree reflection for the incident waves at the antenna working frequency [33][34][35][36]. There are different ways to use metamaterial structures for enhancing the antenna gain, as illustrated in Figure 10.…”

Metamaterials are efficiently homogenizable arrangements of artificial structural components engineered to achieve beneficial and exotic electromagnetic (EM) properties not found in natural materials. Metasurfaces are the two-dimensional analogue of metamaterials consisting of single-layer or multi-layer stacks of planar structures. Both metamaterials and metasurfaces have great potential to be used in a wide range of applications, e.g., antennas, polarization converters, radar cross section (RCS) reduction, and absorbers, to control the amplitude, phase and polarization of the reflected and transmitted EM waves. This chapter presents a brief overview of the known types and applications of metamaterials/metasurface followed by comprehensive analysis of these surfaces for antennas performance enhancement, polarization conversion, RCS reduction, and wave absorption.

“…A circular split ring resonator 33 with the dimension 8 × 8 was presented for the 15.4 GHz improving transmission spectrum with the modification of fractal order. Large dimension utilized for the lower microwave frequency region from 600 to 800 MHz was fabricated using rectangular shaped metallic layer and 2 × 2 array cell was printed to provide engineered magnetic material for the gain improvement with the effective medium ratio 8.84 34 . Parallel LC shaped resonator 35 was introduced wider bandwidth at 5.1 and 10 GHz and Aztec shape metamaterial 36 unit cell with lower effective medium ratio was established for C, X band applications.…”

In this research work, the development of the metamaterial unit cell is used to investigate multifunctional characteristics, exhibit preferable and capable adjustability, reconfigurable by changing the phase response of applied electromagnetic wave. This proposed metamaterial unit cell is analysed by modifying the geometric design of the metallic structure which mitigates the design to reduce the cost for the commercialisation. The resonant frequencies are located from 1.87, 2.55, 4.32, 5.46 GHz. The interaction with the electric field and magnetic field exhibit the polarisation in both planes which enhances the left handed characteristics. The field distribution of electric, magnetic, and surface current is presented with vector fields in different planes to observe the polarisation state. Different thicknesses of dielectric material are utilised to observe the impact of time varying electric and magnetic fields through the proposed metamaterial. The different substrate materials are described the degree of freedom for the implementation in different fields within the functional microwave frequency range.

“…Sistem komunikasi seluler memerlukan perangkat antena yang memiliki dimensi kecil dengan biaya fabrikasi rendah. Beberapa penelitian sebelumnya [7][8][9][10][11][12] telah menjelaskan beberapa teknik untuk mereduksi dimensi dari antena. Dalam penelitian sebelumnya yang dilakukan oleh [13], dimensi antena dapat dikurangi hingga 17,87% menggunakan teknik slot, kemudian metode celah yang diterapkan oleh [14] berhasil mengurangi dimensi hingga 37,5%.…”

Penelitian mengusulkan desain antena mikrostrip pencatu ganda yang dioptimasi dengan menggunakan peripheral slits untuk sistem komunikasi bergerak. Minaturisasi dan pengurangan ukuran antena mikrostrip pencatu ganda telah diselidiki dan dijelaskan dalam makalah ini. Dimensi antena yang diusulkan berkurang menggunakan 3 pasang celah sedangkan frekuensi resonansi 1800 MHz. Berdasarkan hasil simulasi dan optimisasi, dimensi antena yang diusulkan dapat dikurangi hingga 94,81% dibandingkan dengan antena mikrostrip saluran umpan berganda konvensional. Hasil ini menunjukkan bahwa teknik peripheral slits berhasil mengurangi dimensi antena yang diusulkan tanpa mengubah frekuensi kerja antena. Dari proses pengukuran didapatkan nilai koefisien
