STEP 0: Pre-Calculation Summary

Formula Used

Beamwidth = (70*Wavelength)/Parabolic Reflector Diameter
ψ = (70*λ)/D
This formula uses 3 Variables

Variables Used

Beamwidth - (Measured in Radian) - Beamwidth is a term used to describe the angular width of the main lobe of radiation or transmission in the context of transmission lines and antennas.
Wavelength - (Measured in Meter) - The wavelength of an electromagnetic wave is an important parameter in the design and operation of transmission lines and antennas.
Parabolic Reflector Diameter - (Measured in Meter) - Parabolic Reflector Diameter refers to the width of the reflector from one edge to the opposite edge, passing through the center.

STEP 1: Convert Input(s) to Base Unit

Wavelength: 7.8 Meter --> 7.8 Meter No Conversion Required
Parabolic Reflector Diameter: 3 Meter --> 3 Meter No Conversion Required

Beamwidth of Reflector Formula

Beamwidth = (70*Wavelength)/Parabolic Reflector Diameter
ψ = (70*λ)/D

How is gain and beamwidth related?

The beamwidth falls as the gain of the parabolic antenna, or any antenna increases.
Normally the beamwidth is defined as the points where the power falls to half of the maximum, i.e. the -3dB points on a radiation pattern polar diagram.

How to Calculate Beamwidth of Reflector?

Beamwidth of Reflector calculator uses Beamwidth = (70*Wavelength)/Parabolic Reflector Diameter to calculate the Beamwidth, The Beamwidth of Reflector formula is defined as the angular width of the main lobe of a directional antenna's radiation pattern. It is a measure of how wide or narrow the antenna's beam is. The beamwidth determines the coverage area and the concentration of the antenna's radiation in a particular direction. Beamwidth is denoted by ψ symbol.
