Federal University of Technology, Owerri, Nigeriahttps://repository.futo.edu.ng/handle/20.500.14562/1724This thesis is for the award of Master of Engineering (M.ENG) in Communication EngineeringThis study focuses on the Performance Improvement of a Direction Finding System Antenna Using Method of Moment (MoM) Approach. The work was developed to provide an approximate current distribution for a direction finding system antenna by employing the use of Method of Moment on an array of Yagi-uda antenna. The parameters of the experimental antenna were derived and analyzed using Magnetic Vector Potential (MVP) operator. The accurate current flowing through the radiating elements of the direction finding system was analyzed using combination of Method of Moment technique and Magnetic Vector Potential (MVP) operator. The antenna parameters were simulated using MatLab R2010a software tools. From the results obtained, the Average Poynting vector of the designed yagi antenna is 3.73 watt per square metre, and Radiation Intensity value of about 9.400 columns per kilogram. The simulation results also indicated an appreciable increase in directivity of 9.03dBi and enhanced directive gain compared to that of the equivalent log-periodic antenna of 6.5dBi, signifying 2.53dBi enhancement.enAttribution-NonCommercial-ShareAlike 4.0 InternationalYagi antennamoment methodwireless communicationelectromagnetic waveswire antennasultra high frequency (UHF)magnetic vector potential.Department of Electrical/Electronic EngineeringMaster’s Thesis
