Antenna Beamwidth Coverage Calculator
The antenna beamwidth is the angle from where most of the antenna power is radiated. This power is the peak power. The half-power beam width (3dB beam width) is the angle at which the relative power of the antenna is 50% of the peak power in the effective radiated field of the antenna. The antenna beamwidth coverage calculator determines the beamwidth coverage of the antenna when its half-power beamwidth is known at the given product separation distance.
