“…Many research academics have been improving microstrip antenna gain and directivity utilizing various designs, concepts, and materials. Different methods are employed to attain suitable antenna performance characteristics, including reflecting surface [5][6][7], array element [8], fractal boundary [10,11], and metasurface material antenna [9,13], along with unique arbitrary shapes inspired by nature like flower [12]. Al-Gburi et al [14], thorough research employed a printed monopole antenna with a strawberry-shaped radiating patch on an FR-4 dielectric substrate with a coplanar waveguide and frequency selective surface (FSS) to obtain high bandwidth and gain.…”

Mushroom-Cloud-shaped wide slot microstrip patch antenna (MC-MSPA) was discovered and proved to be a viable option for wideband applications in this research study. The given antenna has a high radiation and wideband reflection coefficient of 134.47% from 1.15 GigaHz to 5.87 GigaHz for |S 11 | < −10 dB. This antenna has a peak gain of 6.47 dBi at 4.6 GigaHz and 6.1 dBi at 5 GigaHz, as well as an return loss of 47.37 dB at 1.88 GHz. MC-MSPA has optimised dimensions of 0.73λ g × 0.72λ g × 0.02λ g . Furthermore, a reflecting surface of a 7 × 7 square-shaped array beneath the ground plane has been included to provide even higher gain and directivity. The proposed MC-MSPA+RP antenna has a fractional bandwidth of 63% with dual bands from 1.438 to 2.782 GigaHz and 38.89% from 3.964 to 5.878 GigaHz, with a peak gain of 9.657 dBi, maximum directivity of 10.44 dBi at 5 GigaHz, and maximum return loss of 54 dB at 4.9 GigaHz. Reflector plate electrical dimensions have been enhanced to 0.87λ g × 0.87λ g × 0.24λ g . The proposed design improves gain and directivity, both of which are important for WLAN and Wi-MAX applications.

“…This structure resonates at six different frequencies suitable for GSM, Wi-MAX, Wi-Fi, and WLAN applications. In [13], a circularly shaped fractal antenna (70 mm × 70 mm × 1.57 mm) printed on an RT Duroid 5880 substrate for ISM band application is reported. The antenna structure is implemented by rotating the square patch at a specified angle.…”

In this paper, a low-profile fractal antenna with square ring slots is reported. The newly proposed fractal antenna includes circular ring radiating elements with orthogonally placed square shape slots to achieve ultra-wideband operation. The compact antenna (32 × 28 × 1.6 mm 3 ) is designed and fabricated on an FR4 dielectric substrate, and measurements are performed to validate the simulation results. The simulated and measured results demonstrate that the antenna has −10 dB impedance bandwidth of 9.4 GHz from 4.2 to 13.6 GHz in the ultra-wideband frequency. The measured results reveal that the antenna has omnidirectional radiation characteristics with peak gain of 5 dB in the desired band of operation. The proposed antenna has low cross polarization of −28 dB and radiation efficiency about 88% in the operating bandwidth. The large bandwidth, low cross polarization, and stable radiation characteristics confirm that the proposed antenna may be suitable for ultra-wideband applications.

A flexible and high gain saw-tooth-shaped boundary fractal wearable antenna is anticipated for WBAN applications. A square shape is converted to the saw-tooth-shaped boundary by sequentially rotating the square at an angle of 45° and overlaid on one another and repeated the same for three iterations. The geometry is built on a flexible jeans substrate, and the total size of the anticipated antenna is 0.583λ × 0.583λ × 0.02λ at 2.4 GHz. A prototype has been made to test its suitability for wearable applications' gain, bandwidth, and efficiency. The results revealed that the proposed antenna provides an impedance bandwidth of 4.2% and a peak gain of 5.76 dBi at the 2.45 GHz ISM band. The anticipated antenna is wrapped around foam cylinders of radii 70 and 50 mm to test the stability and deformability of its performance. The full ground plane isolates the antenna from the human body contributing to the lower SAR values. The simulated maximum achieved specific absorption rate (SAR) of 0.3025 and 1.16 W/kg for 10 and 1 g of average tissue for the input power of 100 mW, respectively, found within the standards as per FCC. The peak gain, compact size, and SAR permanence made the anticipated antenna a worthy candidate for wearable on/off body applications.
