Miniaturized Folded-Slot Antenna using Triangle Koch Fractal Technique for Satellite Applications

In this paper the fractal iteration technique has been applied to obtain the second iteration of folded slot antenna. This fractal antenna has been designed on substrate Roger RT6002 with dielectric constant \({\varepsilon }_{r}=2.94\) and substrate thickness \(h=0.76\) mm. The results show that there is a relationship between the iteration number and the resonance frequency. With an increase in the number of iterations, the resonance frequency decreases with a constant ratio. The use of fractal structures to design antennas makes them more miniaturized. The simulation and optimization are performed using CST Studio suite. The result shows that the operating frequency decreased from 8.24GHz to 7.33GHz.
