Abstract

Generally, fractals antenna possessed a tremendous amount of potential in providing a multi-band solution through property of self-similarity that the fractals shape has. This thesis has focused on the modification of original Sierpinski fractal shape patch antenna onto a typical bow-tie antenna, providing additional parameters to optimize in order to get the required radiation characteristic. A Sierpinski Fractals Bow-Tie Antenna is designed by stacking an intermediate layer of a triangular patch whose size is equal to that of the triangular hole in the fractal structure. The gap is introduced for improving the radiation pattern. A prototype of the antennas is fabricated with polylactic acid (PLA), a high-strength thermoplastic material that are fabricated by using 3D printing technology. Due to complex geometry of fractal designs, these antennas are capable of resonating at multiple frequencies, making them excellent wideband antenna
