“…Chiral metamaterials are used as artificial superstrate over CP antenna [58]. Circularly polarized array antennas are placed as primary source in some of the previous research works [59,60]. Wide axial ratio bandwidth of RCA has been reported in the literature, where sequentially rotated phase feeding patch array antenna [61] is used as a primary source.…”

“…Over the last two decades, metamaterials have become increasingly popular in the antenna community due to their ability to improve the performance of antenna systems. They offer advantages such as bandwidth enhancement, gain improvement, miniaturization, stealth capabilities, and reductions in mutual coupling [73][74][75][76][77][78][79][80]. Combining fractal metamaterials with antennas is an innovative approach in EM technology.…”

This paper provides an overview of fractal antennas and metasurfaces, exploring their design principles, performance, and applications. Fractal antennas, incorporating self-similar geometric shapes, offer several advantages, such as their multiband operation, compact size, and improved performance. Metasurfaces, on the other hand, are two-dimensional structures composed of subwavelength unit cells and are designed to achieve advantageous and unusual electromagnetic properties by enabling precise control over electromagnetic waves. This paper discusses the fundamental concepts of fractal antennas and metasurfaces, compares their characteristics, and presents the latest advances in research. Additionally, it highlights applications in wireless communications, energy harvesting, sensing, and beyond.

“…This is especially true for the circularly polarized (CP) microstrip antenna which owns additional advantages of imposing less strict restrictions on orientation of the transmitter and receiver and mitigative multi path effects. A survey of recent literature indicates that a considerable amount of efforts have been devoted to the antennas with CP, for instance, CP antennas for bandwidth enhancement by using left handed (LH) metamaterial transmission line (TL) [8] and reactive impedance substrates [9], respectively, CP antennas with gain and directivity enhancement [10][11][12][13], omnidirectional radiations [14][15][16] and even dual-band or multifrequency operation with radiation pattern selectivity and polarization diversity [16][17][18][19][20][21][22][23][24][25].…”

Abstract-A novel triple-band single-fed compact microstrip antenna with varied polarization states and radiation patterns is proposed based on two-dimensional artificial metamaterial transmission line (TL). The TL element is composed of complementary split ring resonators (CSRRs) etched in the ground plane and a capacitive gap embedded in the stepped-impedance conductor line. By inserting a 2 × 2 array of the original element in conventional patch and feeding the resultant structure with an annular-ring slot along the diagonal, an antenna working in three resonant modes (n = −1, n = 0, and n = +2) is engineered at three specific well-separated frequencies f −1 = 1.5, f 0 = 2.4 and f +2 = 3.5 GHz, respectively. As a result, both the numerical and experimental results illustrate that the antenna exhibits a patch-like radiation with pure linear polarization in the n = −1 mode, a monopolar radiation with circular polarization in the n = 0 and also an asymmetric quasi monopolar radiation with a hybrid linear polarization in the n = +2 mode. The antenna features compact whose patch occupying only an area of 0.246λ 0 × 0.246λ 0 × 0.03λ 0 at f −1 and exhibits groups of advantages such as high radiation efficiency. Moreover, the proposed prescription, free of any metallic via, perturbation structure and complicated feeding network, is of practical value and opens an alternative avenue toward new types of antenna with agile polarization capability and versatile radiation patterns.
