Sierpinski Carpet Fractal Microstrip Antenna for Improved Bandwidth using Stacking Technique with Stripline Feeding
In this paper, the authors outline the design of Sierpinski carpet fractal microstrip antenna up to third iteration is proposed. Prototype antenna is designed on FR4 substrate with thickness of 1.6mm whose relative dielectric constant of 4.4 using microstrip line feeding. These antennas are optimized to operate under various specified bands between 2-14GHz. 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 microstrip line feeding to enhance the bandwidth.
