“…At this point, the fractal miniaturization approach promises an effective way to reduce the antenna dimension while keeping the length of the effective EM wave current's route due to its self-similarity and space-filling characteristics. Various works have investigated the fractal antenna design, including the Koch-modified antenna [47], the Minkowski fractal antenna [48], the Fern-fractalshaped microstrip antenna [49], and the Peano-Gosper fractal antenna [50]. In Table 1, we have summarized several works on implantable fractal antennas.…”

Fractal structure is a unique geometry that can be seen in many objects in nature, such as clouds, coastlines, DNA, trees, and even pineapple. This structure has manifold geometries, self-similarities, and space-filling properties. Due to these properties, fractal geometries are preferred to miniaturize an antenna in wireless communications. There are many cases that require a small compact antenna, including in-body communications. In this article, we present a review of the recent trends and advancements in fractal antenna research, especially in the miniaturization of implantable antennas for in-body communications. The review is derived from articles that are gathered from online libraries such as IEEE, PubMed, Nature, MDPI, Elsevier, and Google Scholar. As a result, we have collected more than 60 articles related to fractal-implantable antenna and in-body communications. Indeed, many researchers have proposed an implantable compact antenna with fractal geometries in the last decades. Fractal geometry allows a longer electrical length to be routed in a smaller area of the antenna. However, several things remain challenging in designing a fractal antenna, including bandwidth, fabrication complexity, and intercell interference.

“…Sharma et al [31], also employed the metamaterials such as edge coupled parasitic SRR in the structure of fractal antennas to obtain the multi band frequency response. Also, the HFA is designed by Sharma et al [32] by using three fractals such as Peano-Gosper, Koch and fractal Minkowski for multi standard communication applications. Sharma et al [33] also inspected the HFA using CPW fed for UMTS/PCS/Wi-MAX/WLAN applications.…”

In this manuscript the design of a high isolation Multiple Input Multiple Output (MIMO) Hybrid Fractal Antenna (HFA) has been presented for 5G and other wireless standards in wider operational frequency range from 1 to 30GHz. The proposed MIMO antenna has been developed by the hybrid combination of Minkowski and Meander fractal curves on a partial octagonal shaped radiating patch. Fractional ground plane is used for the assembly of antenna in the initial phase and, further the T-stub has been exploited on the ground plane to expand the isolation between the radiating elements. The structure of Meander and Minkowski hybrid fractal curves is generated by using iterative function system (IFS) technique. The dimensions of proposed antenna are optimized using particle swarm optimization gravitational search algorithm (PSOGSA).A wider impedance bandwidth 29GHz (187.09%) has been attained in the operative frequency range by using merged fractal structure on proposed patch with tapered transmission line feed. The optimized structure of proposed hybrid MIMO antenna has been fabricated on Rogers RT/duroid 5880 substrate material of height 1.6mm. The performance parameters of the projected antenna have been measured and analysed .The obtained experimental results are highly correlated with simulated ones. Performance diversity parameters of designed antenna like CCL, DG, ECC, TARC and MEG fall within working limits in the frequency range of interest. Also the developed antenna retains high isolation between − 30 to -50dB in the desired frequency range .The proposed model of antenna can be useful for 5G 3.5GHz band, 5G NR (New Radio) frequency bands (3.3–5.0GHz), LTE band 46 (5.15–5.925GHz), EU (European Union) 5G frequency band (5.9–6.4GHz), 5G 26GHz frequency band and other wireless standards in the frequency range from 1 to 30GHz.

“…This configuration was proposed by the authors in [10], where the band 0.1GHz -30 GHz was continuously covered, with a size area of 60 × 60 mm 2 . In [11], the authors presented a geometrical structure that incorporated a combination of the Peano-Gosper, Koch and Minkowski fractal curves. It covered a frequency range 1-20 GHz with maximum gain of 5.08 dBi at 3.4 GHz.…”

This paper presents two different antenna modules at two different bands with a compact size structure that is used for both of mm-Wave and microwave bands, with the objective of keeping the size as minimum as possible. The presented structure consists of two integrated modules with overall dimensions of 24 × 15 × 0.787 mm 3 and is implemented on a Rogers RT5880 substrate. The first module is designed to resonate at 25.75 GHz with bandwidth of 4.15 GHz. The length of this module is taken as a constraint in designing the second module, which is the microwave one. This module is designed to have resonance frequency of 5.45 GHz with bandwidth of 1.12 GHz. The two modules are etched on the same substrate in an integrated fashion to give the required structure with two separate feeds and a separation gap between them in the ground plane. The proposed antenna structure is simulated using the CST-MW studio simulator, where it is found that for the mm-Wave module, the band's gain is 5.58 dBi and the efficiency is 0.87 at 25.75 GHz. As for the microwave module, the gain is 2.45 dBi and the efficiency is 0.77 at 5.45 GHz. The proposed structure is implemented practically and the relevant measures agree with the simulated ones. A comparison of the proposed structure with other designs available in literature shows that it exhibits the minimum size among them, while keeping the other parameter values of comparable orders. The proposed structure is suitable for being used in 5G applications where both of the microwave and millimeter-wave bands are utilized. Microstrip antenna,, mm-Wave fifth generation (5G), DGS.
