The Antenna Beamwidth Calculator serves as a pivotal tool in the realm of antenna design, offering a straightforward method to determine the angular width of an antenna's radiation pattern. This essential metric, measured in degrees, aids in evaluating an antenna's coverage area and directional capabilities.
Formula of Antenna Beamwidth Calculator
The formula used to calculate Beamwidth is:
Beamwidth (in degrees) = 2 * arctan (D / (2 * L))
Where:
- Beamwidth: Represents the angular spread of an antenna's radiation pattern.
- D: Denotes the diameter of the antenna dish or aperture in meters.
- L: Signifies the wavelength of the electromagnetic wave in meters.
This formula provides a fundamental understanding of how the Beamwidth correlates with the physical attributes of an antenna, influencing its transmission and reception capabilities.
