Antenna Beamwidth Solution

STEP 0: Pre-Calculation Summary

Formula Used

Antenna Beamwidth = (70*Wavelength)/Antenna Diameter
b = (70*λ)/d
This formula uses 3 Variables

Variables Used

Antenna Beamwidth - (Measured in Radian) - Antenna Beamwidth refers to the angular extent of the main lobe of the radiation pattern of an antenna.
Wavelength - (Measured in Meter) - Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.
Antenna Diameter - (Measured in Meter) - Antenna Diameter refers to the Largest dimension of the antenna aperture.

STEP 1: Convert Input(s) to Base Unit

Wavelength: 90 Meter --> 90 Meter No Conversion Required
Antenna Diameter: 8990 Meter --> 8990 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

b = (70*λ)/d --> (70*90)/8990

Evaluating ... ...

b = 0.700778642936596

STEP 3: Convert Result to Output's Unit

0.700778642936596 Radian -->40.1516586131798 Degree (Check conversion here)

FINAL ANSWER

40.1516586131798 ≈ 40.15166 Degree <-- Antenna Beamwidth

What are lobes in Antenna?

In an antenna radiation pattern, the lobe that (a) contains the maximum irradiance, i.e., contains the direction with the maximum radiation intensity, i.e., maximum radiation, and (b) usually contains the largest amount of radiated power compared to any other lobe.

How to Calculate Antenna Beamwidth?

Antenna Beamwidth calculator uses Antenna Beamwidth = (70*Wavelength)/Antenna Diameter to calculate the Antenna Beamwidth, Antenna Beamwidth refers to the angular extent of the main lobe of the radiation pattern of an antenna. It represents the angular coverage or spread of the antenna's radiation pattern in the direction of maximum radiation. The antenna beamwidth defines the angular range over which the antenna exhibits significant radiation or reception. Antenna Beamwidth is denoted by b symbol.

How to calculate Antenna Beamwidth using this online calculator? To use this online calculator for Antenna Beamwidth, enter Wavelength (λ) & Antenna Diameter (d) and hit the calculate button. Here is how the Antenna Beamwidth calculation can be explained with given input values -> 2300.521 = (70*90)/8990.

FAQ

What is Antenna Beamwidth?

Antenna Beamwidth refers to the angular extent of the main lobe of the radiation pattern of an antenna. It represents the angular coverage or spread of the antenna's radiation pattern in the direction of maximum radiation. The antenna beamwidth defines the angular range over which the antenna exhibits significant radiation or reception and is represented as b = (70*λ)/d or Antenna Beamwidth = (70*Wavelength)/Antenna Diameter. Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire & Antenna Diameter refers to the Largest dimension of the antenna aperture.

How to calculate Antenna Beamwidth?

Antenna Beamwidth refers to the angular extent of the main lobe of the radiation pattern of an antenna. It represents the angular coverage or spread of the antenna's radiation pattern in the direction of maximum radiation. The antenna beamwidth defines the angular range over which the antenna exhibits significant radiation or reception is calculated using Antenna Beamwidth = (70*Wavelength)/Antenna Diameter. To calculate Antenna Beamwidth, you need Wavelength (λ) & Antenna Diameter (d). With our tool, you need to enter the respective value for Wavelength & Antenna Diameter and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
