“…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.
