Return loss validation of a novel cantor based antenna using FIT and FDTD

Abstract

In this paper, return loss of a newly proposed cantor based multifractal multiband monopole antenna is analyzed using two numerical methods for validation. The Finite Integration Technique (FIT) and the Finite Difference Time Domain Method (FDTD) are used for analysis. The proposed antenna has multiband characteristics covering several wireless applications in Ultra Wideband (UWB) including WLAN 2 .4 GHz applications. A commercially available simulator CST (Based on FIT) and a MATLAB program based on FDTD method (Written as a simulator) are utilized for observing return loss of the proposed antenna. Then a resonance comparision is done which shows great analogy i.e. validates the result of one numerical method against another one.
