The angle between the -3 dB points is known as the half-power beam width (or simply beam width). Beamwidth is usually but not always expressed in degrees and for the horizontal plane. It refers to the main lobe, when referenced to the peak effective radiated power of the main lobe. See more The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. In filters, optical filters, and electronic amplifiers, … See more This occurs when the output voltage has dropped to $${\displaystyle 1/{\sqrt {2}}}$$ (~0.707) of the maximum output voltage and the power has … See more • Antenna aperture • Angular resolution • Full width at half maximum See more In antennas, the expression half-power point does not relate to frequency: instead, it describes the extent in space of an antenna beam. The half-power point is the angle off See more WebBeamwidth provides a metric of angular resolution for antennas. Most commonly, beamwidth is defined by either the half-power beamwidth (HPBW) or the null-to-null spacing of the main lobe (FNBW). To find the … WebHalf power beam width (B hp) The half power beam width represents the angle within the main lobe of the antenna where its gain is above 50% of the peak gain (angle between -3dB points of the main lobe).
