How to Evaluate Antenna Beamwidth?

Antenna Beamwidth evaluator uses Antenna Beamwidth = (70*Wavelength)/Antenna Diameter to evaluate 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 evaluate Antenna Beamwidth using this online evaluator? To use this online evaluator for Antenna Beamwidth, enter Wavelength (λ) & Antenna Diameter (d) and hit the calculate button.

FAQs on Antenna Beamwidth
