This paper presents ultra wide band circular fractal antenna. The antenna has been fed with coplanar waveguide (CPW) feed. This fractal antenna has been designed and fabricated on FR4 substrate εr = 4.3 and thickness h = 1.53 mm with initial diameter of solid circular disc 15 mm. The experimental result of circular fractal antenna exhibits the ultra wide band (UWB) characteristic from 3.295 GHz to...
This paper presents the design of an ultra wide band (UWB) antenna with CPW-fed. The antenna has been designed on FR4 substrate ??r = 4.3 and thickness 1.53 mm. The antenna has been fabricated and tested using VNA. The experimental results of this antenna offer ultra wide bandwidth from 2.86 GHz to 14.38 GHz. This corresponds to the impedance bandwidth 11.42 GHz and 132.48 %. The experimental results...
This paper presents the design of a star shaped circular microstrip fractal antenna. This star shaped circular microstrip fractal antenna has been designed on substrate with dielectric constant epsivr = 4.3 and thickness h = 1.53 mm. The antenna has been simulated using FDTD technique with dimension a = 40 mm. The simulated result shows the multiple resonances at 0.81 GHz, 1.47 GHz, 2.47 GHz and 3...
This paper presents the design of Fractal Microstrip Yagi Uda Antenna. This antenna has been modeled by incorporating fractal geometry in microstrip technology applying the conventional Yagi-Uda principle. The antenna has been designed on substrate epsivr =4.3 and h=1.53 mm using Sierpinski gasket. The Sierpinski gasket as Driver, Reflector and Director of height 80 mm, 83 mm, 77 mm respectively are...
