Analysis of microstrip rectangular carpet shaped fractal antenna

Abstract

The need for miniaturized antenna is ever growing in view of the advancements in wireless communication technology. The conventional microstrip antennas take any shape like square, rectangular, triangle and so on. They provide normally single resonance frequency with high quality factor because of narrow bandwidth. However, the fractal antennas are able to provide either multi-band resonances or broad bandwidth because of the self-similar and space-filling properties. In present paper, a study is made on Sierpinski gasket carpet fractal antenna, for single and multiband applications. Design and simulation is done using HFSS 13.0 software and fabrication is done using photolithography etching method which gives adequate result for this type of antennas. By using vector network analyzer E5071C the designed antennas are tested and various plots like return loss, VSWR, smith chart and polar plot are verified. The designed antennas are used in implantable medical (IMD) applications and other wireless applications. [1-6].
