![]() reported a dual wideband modified Sierpinski square fractal antenna. introduced a stair-shaped fractal antenna that resonated at 3.65, 4.825, and 6.325 GHz. presented a multiband circular fractal antenna with parasitic SRR, which operates at 3, 5, 6.8, 7.5, and 8.5 GHz. designed a multiband plus-shaped fractal antenna with dual frequency bands covering the Global System for Mobile (GSM) band, 5G spectrum band, sub-6 GHz band, Long Term Evolution (LTE) band, and Wireless Local Area Network (WLAN) band. reported a hexagon Koch snowflake fractal antenna shielded the broad bandwidth (3.265–8.2 GHz). designed a fractal antenna for an X-band application it consisted of a four-fold centrosymmetric radiating element. presented an annular ring fractal antenna for wideband operation. investigated a circular fractal antenna with Split Ring Resonator (SRR) stubs for multiband wireless applications. ![]() The findings were then compared to the experimental results, which were found to be in strong agreement. Utilizing CST MWS, the performance of the suggested Sierpinski hexagonal-shaped fractal antenna was achieved. The investigated antenna exhibited good gain with almost omnidirectional radiation patterns. ![]() ![]() These frequency ranges are compatible with a variety of wireless technologies, including WLAN, WiMAX, ISM, LTE, RFID, Bluetooth, 5G spectrum band, C-band, and X-band. According to the measurements, the designed antenna resonates throughout the frequency ranges of 2.19–4.43 GHz, 4.8–7.76 GHz, and 8.04–11.32 GHz. The investigated antenna has a small footprint of 0.19λ 0 × 0.24 λ 0 × 0.0128 λ 0 and improved bandwidth and gain. ![]() The fractal manufactured antenna developed has a Sierpinski hexagonal-shaped radiating element and a partial ground plane loaded with three rectangular stubs and three rectangular slits. This paper introduces a new tri-wideband fractal antenna for use in wireless communication applications. ![]()
