WebThe first null beamwidth is useful in finding out how much antennas will interfere with each other. To get a good (as close to 1 as possible) ratio of half-power beamwidth to first null beamwidth usually requires a larger aperture than for poorer ratios, so is more expensive in terms of area required, and cost and weight of antenna.

WebThe Half Power Beamwidth (HPBW) is the angular separation in which the magnitude of the radiation pattern decrease by 50% (or -3 dB) from the peak of the main beam. From Figure 2, the pattern decreases to -3 dB at 77.7 and 102.3 degrees. Hence the HPBW is 102.3-77.7 = 24.6 degrees. Another commonly quoted beamwidth is the Null to Null Beamwidth. WebDec 3, 2024 · In the radiation pattern of an antenna, the main lobe is the main beam of the antenna where maximum and constant energy radiated by the antenna flows. Beam width is the aperture angle from where most of the power is radiated.
