A Design of Sierpinski Triangular Slotted Sierpinski Fractal Patch Antenna For Multi Band Applications

In this paper, a novel design of Sierpinski Triangular slotted Sierpinski fractal patch antenna is presented. In this work a diagonally triangular slotted sierpinski fractal patch antenna is designed for 4.27 GHz frequency. These fractal antennas are basically microstrip patch antenna. For designing this microstrip fractal patch antenna IE3D simulation software is used. In all fractal antennas FR4 epoxy is used as substrate with height 1.6 mm and dielectric constant 4.4 respectively. For feeding we have used Probe feeding method. In all iteration feeding point is same and radius of feeding point is 0.16mm.nbspnbspnbsp In the base shape a rectangle patch of length 10.56 mm X 15.24mm is chosen as base shape shown in figure1. In the first iteration four triangular patches of 1 mm X 1 mm X 1mm X 1 mm are cut from the geometry( from four corners) at a gap of 0.50 mm.. In the second iteration again four triangular patches of 1 mm X 1 mm X 1 mm X 1 mm are cut at a gap of 0.25 mm from the triangle of the first iteration.. Same procedure is done in third iteration.
