“…HFA using Sierpinski Carpet and Minkowski fractal is designed by Sharma et al [34] for applications like C-band, Wi-MAX, hi speed point to point wireless communication and X-band. By using above mentioned fractal and hybrid fractal geometries numerous types of fractal antennas are designed which are suitable for 5G communications [35][36][37][38][39][40][41][42][43][44][45]. MIMO antennas are proficient candidate of integrally justifying the properties of network quantity, multipath, producing a best-quality dependability of the link, channel volume, gain exposure without challenging more impedance bandwidth for additional enlightening the quantity and spectrum effectiveness of MIMO antennas and the massive MIMO emanated into presence, somewhat a development of MIMO is essentially clustering the antennas together at the receiver as well as transmitter.…”

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.

“…23 The major challenges of existing microwave sensor-based tumor detection techniques are nonoperability in the UWB frequency band, trade-off among high frequencies with the depth of penetration, big size of a UWB sensor, inadequate mimicry of dielectric properties of human tissues, and not meeting the SAR requirements as per FCC guidelines. Therefore, the main aim of this research article is to design a miniaturized modified tapered feedline [24][25][26][27][28] patch antenna (MTFPA) with a defective ground plane operating in the UWB band for radar-based biomedical imaging applications.…”

This article proposes a low‐profile ultra‐wideband (UWB) antenna for breast tumor detection using the monostatic radar‐based microwave imaging (RBMI) technique. The proposed UWB antenna consists of a circular patch and ground plane along with a modified tapered feed line having a total size of 13 × 9 × 1.6 mm3. The designed antenna operates from 4 to 11 GHz based on a −10 dB reflection coefficient with a peak gain of 9.5 dBi at 4.8 GHz. Experimental validation is carried out after fabricating the prototype of the UWB antenna and the breast mimic. The measured backscattered signals are captured using the vector network analyzer (E‐5063A) by keeping the antenna at 10 mm from the breast phantom. After that, post‐processing of the measured data is done to detect the exact depth and location of the malignant tissue. The proposed antenna uses UWB band frequency of operation because it has some unique features, that is, it provides immunity to multipath fading, has a simple design, has a low cost of fabrication, and has biological friendliness. Moreover, due to the proposed antenna's resonance at a lower resonant frequency better depth of penetration is achieved in human body phantoms and the proposed antenna provides specific absorption rates (SAR) of 0.877 W/kg over 1 g of tissue at 4.8 GHz, which is an acceptable limit for SAR as per FCC guidelines. Therefore, the proposed antenna and monostatic RBMI technique are good candidates for breast tumor detection.

“…The distinct fractal geometries have been used by the researchers to design the antenna useful for 5G applications. [46][47][48][49][50][51][52][53][54][55][56] MIMO antennas are capable of inherently mitigating the effects of multipath, network throughput, causing a better-quality link reliability, gain, channel capacity, coverage without requiring additional bandwidth, and diversity performance because of spatial (or signaling) degree of freedom. For further improving the throughput and spectrum efficiency of MIMO antennas, the massive MIMO came into existence, rather it is an expansion of MIMO which basically groups together antennas at the transmitter and receiver.…”

The comprehensive review of hybrid fractal antenna (HFA) has been presented in this article. Distinguished researchers have designed, analyzed, and investigated numerous types of HFA's as per the requirement of the market. Firstly, it gives introduction about the fractal antennas (FAs) along with the need of integration of the fractal geometries then research motivation. The extensive literature survey has been divided into three different parts as, fusion of same type of fractal geometries, amalgamation of two distinct fractal geometries and concoction of three different fractal geometries, further, the comparative analysis among these HFA's has been made on the basis of their size, geometries used for designing, number of resonant frequency bands, gain, bandwidth, radiation efficiency, circular polarization, and their applications. The juxtaposition among different HFA's has also been delineated in tabular form for more limpidity along with the findings of individual research article. The challenges faced by researchers while designing the antennas are also being portrayed in this article. This review may be supportive for the novices to carry out their research on HFA as such type of comparative analysis on HFA's is not existing in the open state of art literature as per best of authors knowledge.
