SIERPINSKI CARPET FRACTAL MICROSTRIP ANTENNA FOR IMPROVED BANDWIDTH USING STACKING TECHNIQUE WITH PROBE FEEDING

This research article outlines Sierpinski carpet fractal microstrip antenna for bandwidth enhancement using probe feeding technique from reference to third iterations. Prototype antenna is designed on FR4 substrate with thickness of 1.6 mm whose relative dielectric constant of 4.4. These antennas are optimized to operate under various specified bands between 2-14 GHz. Simulation is carried out using IE3D simulator and it is found that the simulated results are in good agreement with the experimental results. Stacking techniques are also implemented on the designed antenna using probe feeding for further enhancement of bandwidth. Comparison is carried out with reference to without and with stacking method.
