Design and Analysis of Ultra Wide Band Giuseppe Peano Fractal Antenna at Different Height Level of Substrate

Abstract: In this paper microstrip patch antenna is designed for ultra wide band application. Giuseppe Peano algorithm is applied on microstrip patch antenna with rectangular patch of size 30� 24 mm2. Coaxial Feed line is used with the patch antenna and results are carried out by using FR-4 as dielectric substrate. The proposed antenna obtained an ultra wide band of 4.94GHz bandwidth having minimum return loss of �32.73dB. The maximum gain produced by the proposed antenna in this ultra wide band range is 2.37 dBi. Hence, the proposed antenna covers C and X band so it can be used for RADAR applications. The change in antenna height is also analysed. Design and simulation is carried out using IE3D simulation software.
