- Abstract
In this work, a super-wideband (SWB) Sierpinski triangular fractal antenna has been proposed. Keeping electrical dimension (ED) small and bandwidth dimension ratio (BDR) high is a big challenge in SWB antenna design. Sierpinski triangular fractal, slotted and tapered grounds have been used to meet these challenges with a wide operating frequency bandwidth. Operating range of the antenna is from 1.6 to 45 GHz, with a gain more than 1 dBi, bandwidth ratio of 28.1:1, VSWR less than or equal to 2, and with a reflection coefficient (S11) less than − 10 dB. ED of the proposed SWB antenna is 0.12λk × 0.14λk, here λk is the wavelength as per the lowest operating frequency. FR4 material is used as substrate to design and fabricate antenna. Results are measured till 20 GHz which are found quite promising in terms of − 10 dB impedance bandwidth. BDR of the designed antenna is 11,087.3 and ED are small which proves the design effectiveness. Proposed SWB antenna is useful for multiple bands such as WiMax, WiFi, Fixed Satellite Services, Radio Navigation, L, S, C, X, Ku,and Ka bands.
