Abstract
This paper reports the propagation characteristics of a 13- element 640MHz Yagi antenna.The Yagi-Uda antenna is a highly directional antenna and in the transmit mode propagates electromagnetic energy in the direction running from the dipole or driven element toward the director and is sensitive to incoming electromagnetic energy in the receive direction. In this study, NBS 688 technical notes and antenna design curves were used and the resulting antenna estimate was modeled. The simulation and optimization was carried out using 4NEC2 antenna design software. Verification of the optimal design was achieved using EZNEC v.6.0 antenna modeler. The simulation result showed Antenna characteristics such as input impedance, radiated power, efficiency and far-field radiation pattern.
