Description
Summary:Word processed copy. === Includes bibliographical references (leaves 67-69). === Two applications of FEKO are reported. The first application is investigating how antennas propagate. reflect, and the difference in transmit and receive signals in various ground media. Results of the ground penetration simulations done in FEKO (MoM- Method of Moment) is compared to Finite Difference Time Domain (FDTD) results simulated by Mukhopadhyay with the same physical model. The second application is to model and fabricate an ultra wide-band antenna with implementation of the fat dipole design. The design considerations applied to improve antenna performance include antenna feed configurations, substrate width, aperture dimension, cavity implementation, terminating resistance. antenna impedance and balun matching. After the design process was completed, fabrication of the antenna took place and the design validated.
