Printed Monopole Antenna for Ultra Wide Band (UWB) Applications

The thesis is the outcome of the exhaustive theoretical and experimental investigations performed on Printed Monopole Antennas loaded with different geometries .The work presented in this thesis describes the development of a 3D- FDTD(Finite Difference Time Domain) Modeller using MATLAB for the numerical computation of the radiation characteristics of the antenna. The predicted results are verified experimentally and also through simulation using Ansoft HFSS.The effect of top loading of the monopole with different geometries ,the dimensions of the loading patch and ground plane and the material parameters of the dielectric substrate upon the radiation performance of the antenna is studied in detail. Optimized Printed Monopole antennas suitable for Ultra Wide Band (UWB) applications have been developed.
