In this study, the electric and magnetic fields that a short dipole antenna radiates will be modeled, simulated, and their properties in the far-field region particularly at low frequencies will be examined. By investigating the often-overlooked feature of radiated field characteristics, the study aims to provide a deeper knowledge of field behavior in wireless networks, where dipole antennas are often used. The study simulates the electric and magnetic fields produced at far-field distances by a dipole antenna using Python software. The link between wavelength and field strength is investigated using mathematical models that characterize the far-field behavior, which includes equations for far-field distance. The simulation takes into consideration variables like operating frequency, antenna length, and the environment in which it operates, enabling a thorough examination of the fields. The changes in the field components with greater separation from the antenna and the impact of low-frequency operation on the propagation are examined by analyzing the data. According to the calculations, when one gets farther away from the dipole antenna, there is a predictable decline in both the magnetic and electric fields. At far-field distances, the field components especially the angular and radial components display unique behaviors that are consistent with theory. The findings demonstrate how frequency affects field distribution, with decreased frequencies resulting in longer far-field distances and a slower rate of field strength degradation. The study made clear how crucial precise modeling of the radiating fields from dipole antennas is to the efficiency of wireless communication networks. The results show that operating at low frequencies results in larger far-field zones, which may have implications for wireless system design and implementation. Engineers can guarantee higher-quality RF propagation and enhance antenna performance by comprehending these features.
