Sierpinski Bow-Tie antenna with genetic algorithm

Abstract

In this present work, the author has presented Sierpinski Bow-Tie antenna which is meant for the perspectives of triple bands. The designed antenna as made to resonant from 2GHz to 11GHz focusing on covering the aspects of 2.211–2.348GHz, 4.777–5.150GHz and 8.874–10.12GHz. As a result, it produces good coverage of applications, gain of 10.29dBi at highest frequency level, broadside radiation pattern and most importantly, the multiple band performance is achieved. Rogers RT Duroid 5870 substrate is used as it has a permittivity value of 2.33 with the console of the FDTD domain solver in the form of CST-MWS. The main motive behind this design is that on previous occasions, the gain factor is, as always compromised due to lagging in constructional point of view where antennas working for multiple bands suffer a lot, which is pretty much as achieved in this case. A complete explanation regarding the design of Sierpinski Bow-Tie antenna with its behavior has been presented. Genetic algorithm, electromagnetic optimizer highlights on parametric variation of the antenna. ADS platform is used for providing the lumped equivalent model analysis for designed antenna.
