“…In [99], a single patch antenna is proposed to achieve the same directivity as an array with an equivalent area but without using the complex feeding network. In [100], a CPW-fed reconfigurable antenna using crescent-shape fractal geometry is presented where the frequency reconfigurable approach is obtained by using RF PIN diodes, resistor, and inductors. The design allowed the reconfigurable switching up to eight frequency bands between 1.46 and 6.15 GHz.…”

In mathematical definition, a fractal is a self-similar subset of Euclidean space whose fractal dimension strictly exceeds its topological dimension which in turn involves a recursive generating methodology that results in contours with infinitely intricate fine structures. Fractal geometry has been used to model complex natural objects such as clouds coastlines, etc., that has space-filling properties. In the past years, several groups of scientists around the globe tried to implement the structure of fractal geometry for applications in the field of electromagnetism, which led to the development of new innovative antenna configurations called “fractal antennas” which is primarily focused in fractal antenna elements, and fractal antenna arrays. It has been demonstrated that by exploiting the recursive nature of fractals, several marvellous kinds of properties can be observed in antennas and arrays. The primary focus of this article is to provide a compressed overview of the developments in fractal-shaped antennas as well as arrays over the last few decades where the most prominent contributions mostly from IEEE journals have been highlighted. The open intention of this review work is to show an encouraging path to antenna researchers for its advancement using fractal geometries.

“…Many methods have also been used to design multiband antennas, such as fractal-structure antennas, geometric shapes, Koch snowflakes, and Hilbert curves. Fractal antennas have been mainly designed following two different methods, namely, self-similarity [11,12] and space filling [13,14]. Self-similarity in fractal antennas permits the achievement of similar surface current distributions in different planes as well as multifrequency characteristics; space filling enables the increase of the antenna electrical length [15,16].…”

This work proposes a novel multiband slotted planar antenna with a “回” structure, which is similar to an ancient Chinese window grille structure. The antenna is suitable for wireless applications, including the second-generation (2G), third-generation (3G), fourth-generation (4G), and fifth-generation (5G) technologies, as well as WLAN and navigation applications. The proposed antenna is based on the structural characteristics of a conventional monopole antenna, which combines the advantages of a slit structure and microstrip line structure for feeding. It adopts a circular patch with a slit structure placed in it, which is similar to the Chinese classical pane structure. This structure enables an effective reduction of the size of the antenna. The four-sided “回” gaps change the path of current flow and are coupled to each other, improving the impedance matching and radiation characteristics of the entire target frequency band. The antenna covers the frequency ranges of 1.58–1.77 GHz (12%), 2.1–2.50 GHz (17%), 3.61–4.09 GHz (12%), and 4.75–6.5 GHz (36%), permitting more than 10 wireless applications in these 4 frequency bands. This antenna uses an FR-4 dielectric material; the relative dielectric constant of the dielectric plate is 4.4, and the actual dimensions of the antenna are 85 × 70 × 1.6 mm³. The test and simulation results are in good agreement with each other, thus confirming that the proposed design method meets the requirements of various wireless applications.

“…Mandal and Sarkar Pritam have developed a hi-band implementation using different ground structure and extruded base for the additional antennas [1]. A "U" shaped opening to the antenna with ground plane for multi-band operation have proposed an open-space transmission upgrade that keeps super wideband signal execution in pace with changing technology [2], [3]. For data capacity and wire scale reduction multiple fractal forms are utilized.…”

Fractal Antenna are embeds the different scenario of the antenna structures such M, C, O, Triangle, Step, star, and hexagonal etc. in practical application choice of interest. The design scenario improvised with frequency of operation of the different bands ensuring the correct size of the patch, and substrate with design criteria from the mathematical formulations. The proposed Antenna utilizes the Sierpiński gasket with the iteration varying from 0, 1, 2, 3 and 4. The design factor for the size of the antenna is calculated using the mathematical formulations with cut-off frequency at 15, and 17 GHz. This antenna improvised with two set of transmission line with the iteration from 0-1, 3-4 as step induced transmission line, and M shaped transmission line patch as generalist view. The novelty of design model utilizes the python as automated model for each set of iteration criteria and gaps from each subset of Sierpiński gasket. Each set of the antenna parametric values are observed with antenna design lying the Ku and Ka respectively
