Optimal and New Design of T-Shaped Tri-band Fractal Microstrip Patch Antenna for Wireless Networks

Abstract

One of fast growing segment of communication industry is wireless communication which finds application in many areas. Antenna is selected to have small size, it must cover different wireless applications. Characteristics of antenna may be improved by making use of techniques. These techniques are use of fractal geometry, cutting slot in patch and making use of defected ground structure. In this paper, T shape fractal patch antenna is designed using cantor fractal geometry. Here Parametric Analysis of Proposed Antenna has been applied by changing feed points, by changing substrate thickness. By doing this Bandwidth of antenna showed improvement a lot. Comparison is made by changing thickness at different values and characteristics of antenna are compared to obtain best results. After analyzing all we obtain the best results by feed point (0,4,0), FR4 Epoxy as a substrate of thickness 2.4. This antenna is having bandwidth of 130 MHz, 1.3 GHz and 800 MHz. This antenna finds its application for C Band, X band and Wi-Max applications. Best part of this design is that it has good bandwidth in C band which is desired full.
