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 Beam Width?

Beam Width calculator uses beam_width = 1/directivity of antenna to calculate the Beam Width, The Beam Width formula is defined as half-power beam width is the angle between the half-power points of the main lobe, when referenced to the peak effective radiated power of the main lobe. Beam Width and is denoted by b symbol.

How to calculate Beam Width using this online calculator? To use this online calculator for Beam Width, enter directivity of antenna (D) and hit the calculate button. Here is how the Beam Width calculation can be explained with given input values -> 10000 = 1/0.1.

FAQ

What is Beam Width?
The Beam Width formula is defined as half-power beam width is the angle between the half-power points of the main lobe, when referenced to the peak effective radiated power of the main lobe and is represented as b = 1/D or beam_width = 1/directivity of antenna. directivity of antenna measures the degree to which the radiation emitted is concentrated in a single direction.
How to calculate Beam Width?
The Beam Width formula is defined as half-power beam width is the angle between the half-power points of the main lobe, when referenced to the peak effective radiated power of the main lobe is calculated using beam_width = 1/directivity of antenna. To calculate Beam Width, you need directivity of antenna (D). With our tool, you need to enter the respective value for directivity of antenna and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
