Design and Implementation of Hexagonal Koch Fractal Antenna

a hexagonal microstrip patch antenna serves as the core of the design. In order to lower the side lobe level, the hexagonal-shaped patch central portion is also eliminated. A new fractal antenna design is suggested and examined. Finally, a prototype is built and measured in order to validate our concept. The results show that, with a bandwidth of 13.33%, 13.31%and 5.14%, the reflection coefficient remains -10 dB for 2.3125-2.6 GHz, 3.1234-3.5227 GHz and 4.8626-5.191 GHz. According to the simulation research, the antenna can cover two relevant WLAN bands, which are IEEE standards 802.11a (2.4 to 2.4835 GHz) and 5 GHz WLAN, n40 with 2.3 GHz and n41 (2.5 GHz). An antenna with the appropriate size can emit radiation in two bands: the low band, which spans 2.3125 to 2.6 GHz, and the high band, which spans from 4.8626 to 5.191 GHz, with maximum gains of 4.242 dB.
