Abstract

This paper presents the design and analysis of a modified Sierpinski Carpet fractal antenna that contributes ultra wideband characteristics. The proposed antenna with coplanar waveguide-fed structure is compact, which has a total size of 40mm×50mm×1.8mm. An experimental prototype has been fabricated and tested. The measured results show the impedance bandwidth of the proposed fractal antenna that the return loss below -10dB is 8.1 GHz ranging from 2.2GHz to 10.3 GHz. Corresponding 129.6% impedance bandwidth. Analysis of antenna is done using Ansoft High Frequency Structure Simulator (HFSS v 10).Very good agreement obtained between simulation and experimental results.
