Design and simulation of horizontally placed h-shaped fractal antenna

Abstract

The design and simulation of horizontally placed H-Shaped Fractal Antenna is presented in this paper using CST Microwave Studio simulation software and the excitation is provided by using Nickel material for feeding in Y direction, wave guide port feeding method is used.. The simulated result shows that by edge cutting the directivity increases, return loss is very less and the voltage standing wave ratio is nearly equal to unity as the number of iterations increases. In generating multiple frequencies., the horizontally placed H shape fractal structure is advantageous. This antenna can be used in the Wi-Fi due to its better performance in Return loss, VSWR and directivity. In this paper four stages of this antenna is designed and simulated, the third iteration of this antenna is fabricated for Return loss and VSWR. The observations are conducted on antenna parameters such as the return loss for the frequency of 9.5 GHz is-27.6 dB and observed nearly equal value for measured results. The VSWR of both simulated and measured results are also same.
