Calculation Formula

Near-Field Distance (D) = Wavelength (λ) / 2π

Where:
D = Near-Field Distance (m)
λ = Wavelength (m)

Antenna Near Field Distance Calculator Usage Guide

Learn how to use the Antenna Near Field Distance Calculator and its working principles

How to Use the Calculator

  1. Enter the frequency of the antenna in MHz (Megahertz).
  2. Enter the wavelength of the antenna in meters (m).
  3. Click the "Calculate" button to compute the near-field distance.
  4. The result will be displayed in meters (m).

Working Principle

The near-field region of an antenna is the region close to the antenna where the electric and magnetic fields are not in phase and the energy is not entirely radiated as electromagnetic waves. The near-field distance can be calculated using the formula:

D = λ / (2π)

where D is the near-field distance, and λ is the wavelength of the antenna.

Applications

This calculator is useful for engineers and technicians working with antennas in various applications such as wireless communication systems, radar systems, and antenna design.
