Far-field Distance – The far-field distance is the distance from the transmitting antenna to the beginning of the Fraunhofer region or far-field region. The radiation pattern does not change shape in the far-field region as the distance increases. The radiation behavior of antennas is characterized by their far-field radiation pattern. 

This calculator will determine the far-field distance when the frequency of the wave is fed into the input.



The dipole antenna consists of two conductors of equal length oriented end-to-end with the feedline connected between them. The length of the radiating elements determines many of the properties of the dipole antenna: its feed impedance, center operating frequency, whether it is a resonant antenna, etc. As such the dipole length is an important aspect of the dipole antenna parameters. 



Log-Periodic antennas are multi-element directional antennas used for operating in a wide range of frequencies. The most common Log- periodic antenna used are LPDA(Log-Periodic Dipole Array) antennas which are a combination of a dipole antenna and a log-periodic antenna. The construction and operation of a log-periodic antenna are similar to that of a Yagi-Uda antenna. The main advantage of this antenna is that it exhibits constant characteristics over a desired frequency range of operation.
