dc.description.abstractThis paper focuses on the Performance Improvement of a Direction Finding System Antenna Using Method of Moment (MoM) Approach. The work is 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 are derived and analyzed via Magnetic Vector Potential (MVP) operator. The accurate current flowing through the radiating elements of the direction finding system is analyzed using combination of Method of Moment technique and Magnetic Vector Potential (MVP) operator. This helps to avoid the detection of false alarms and inability of the system to detect remote targets. A typical direction finding system Yagi antenna is designed and operated at a frequency range of 0.6- 0.8 GHz. The antenna has a single reflector, an active (driven) element and three (3) parasitic directors. The antenna parameters are simulated using MatLab R2010a software tool. The average pointing vector of the designed Yagi antenna was obtained as 3.73watt per square metre, and Radiation Intensity value of about 9.400 coulomb per kilogram. The simulation results indicate an appreciable increase in directivity of 9.03dBi, an enhanced directive gain compared to that of the equivalent dipole antenna of 1.76dBi, signifying 7.27dBi enhancement.
