Wideband application put a new demand on antennas pertaining to size, gain, efficiency, bandwidth and more. This paper presents the design and analysis of fractal antenna which uses the self similarity property of fractal geometry. This unique property is exploited to develop antenna elements that are wideband and compact possessing highly desirable properties. The presented antenna is circle i...

In this paper we propose the optimization of patch size for a fractal hybrid antenna that can be used in GPS applications. This project is about two different models namely sierpinski gasket fractal antenna and Koch rectangular fractal antenna. A fractal antenna in general is characterized by space filling and self-similarity properties. These fractal shaped antennas have their own unique chara...

A wideband published slot antenna appropriate for wireless code division multiple access (WCDMA) and sustaining the international interoperability for microwave access (WiMAX) applications is planned here. The antenna is fractal line fed and its construction is based on fractal geometry where the resonance frequency of antenna is dropped by applying iteration methods. Fractal antennas are the m...

In this paper, self-similar fractal antenna with electromagnetic band gap (EBG) is proposed and studied. Fractal geometry is a methodology through which size reduction is achieved. Plus shaped fractal antennas with base, first and second iteration of order 1/3 are surrounded with Hexagonal square slotted EBG structures. This is designed on substrate with r=4.4 & h=1.6mm. The designed antenna r...

An analysis and design of a novel planar antenna in corporation with fractal shaped defected ground structure (DGS) for emergency management has been presented in this paper. The conventional ground plane can be replaced by a Fractal DGS ground plane to get miniaturization and better resonating characteristics. Particle swarm optimization (PSO) has been used to identify the geometrical descript...

This paper presents the design of a wheel shaped multiband fractal Antenna. This Fractal antenna has been designed on substrate εr = 4.3 and thickness h = 1.53 mm. This new antenna has been fed with CPW – Fed. The antenna exhibits the multiband resonances due to selfsimilarity in antenna structure. The experimental results indicate that resonant frequencies occur at 1.34 GHz, 2.575 GHz, 4.22 GH...
