Hybrid Design of a Fractal-Shaped GSM/UMTS Antenna

In this paper, the synthesis of a three-band planar antenna working in the GSM (900 and 1800 MHz) and UMTS frequency bands is presented. As reference geometry, a hybrid prefractal shape has been adopted by integrating a Sierpinski-like and a Meander-like structure. The synthesis of the antenna has been performed by optimizing the descriptive geometrical parameters of the reference shape by mean...

Fractal T-Shaped Antenna for WiMAX Applications

Fractal antenna, as name concerns, uses fractal i.e. structure does not change and repeat it when large focus has created upon it. This repetition feature of this antenna provides a great flexibility that it can be designed and can used in different frequencies. Fractal geometry has shown its potential in many fields of engineering and technology. In antenna engineering fractal geometry is very...

Design and Miniaturization of a Novel Fractal Microstrip Antenna for UWB Applications

A novel printed octagonal fractal microstrip antenna with semi-elliptical ground plane is presented for ultra wide band applications. The proposed antenna has a compact size of 20×20×1 mm³. The measured result of the antenna exhibits the ultra wide band characteristics from 2/9 to 14/2 GHz. In this paper, reducing antenna’s size by 35%, the same results were achieved, while small dimension frac...

A Design of E-Shaped Rectangular Fractal Antenna by using Line Feeding Technique

This paper presents a design of E-shaped rectangular fractal antenna and the excitation is provided by using the microstrip line feeding technique. FR4 glass epoxy is used as a substrate material with relative permittivity 4.4, thickness 1.6mm and the resonant frequency is taken as 3.2GHz for the designing of proposed antenna. The three iterations is designed and simulated by using HFSS V13 (Hi...
