Abstract
A novel pattern of fractal antenna deploying Swastika slotted geometry up to second iteration is used for optimization in this paper which enhanced its utilities for S-band. Swastika Slotted Fractal Antenna has been designed and fabricated by the use of FR4 substrate material which has 1.6 mm as its substrate thickness, 4.4 as dielectric constant and 0.02 as loss tangent with help of Zeland IE3D software and MATLAB software. The comparison between Genetic Algorithm and Bat Algorithm revealed that results of BA are superior than GA for the designed geometry. The testing of proposed fabricated antenna has been done by using Rohde and Schwarz ZVL Vector Network Analyzer and obtained experimental results are in good agreement with optimized simulated results. Also, fabricated SSFA resonate at 2.49, 2.70, 2.96 and 3.96 GHz with corresponding values of S-parameter (S11) as ź16.78, ź18.87, ź28.66 and ź11.48 dB respectively.
