Design and fabrication of triangular shaped fractal antenna for cellular communication

In today's world of cellular communication there has been an increasing need for portable and compact communication systems. Fractal is one of the techniques to improve antenna characteristics using fractal geometry. In this paper, fractal antenna is designed on the basis of Sierpinski technique. The triangular shaped fractal antenna is used for cellular application which resonate at frequency 2.1GHz. For designing antenna, FR4 substrate is used which has dielectric constant of value 4.4, feed line, ground optimization and iterations on patch. The prototype covers frequency band from 1.7GHz to 2.47GHz band. The proposed antenna has been designed and simulated using High Frequency Structure Simulator (HFSS) version 13.0 and provides better return loss, low VSWR, larger bandwidth, good impedance value.
