Analysis of Microstrip Triangular Fractal Antennas for Wireless Application

Abstract: The 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 triangular 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.
