Area of a sphere A1 = 4*pi*R^2, Area of a spot where energy will be concentrated in a directional antenna is A2 = 2*pi*R^2 * sin (alpha), where alpha is a beam width angle. In this case math holds only for alpha = 0..90 degrees (hemisphere).

WebHalf the power expressed in decibels is −3 dB, so the half power beamwidth is sometimes referred to as the 3 dB beamwidth (θ 3) or as the Half Power Beam Width (HPBW). Both horizontal and vertical beamwidths are usually considered. WebThis tool can help you calculate an antenna’s maximum (beamwidth) coverage from a specified distance, as well as its half-power beamwidth. Additionally, this tool can help you determine the actual field intensity or power density (in V/M) at a given distance with a known antenna gain.
