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. The two main considerations of this beam width are Half Power Beam Width (HPBW) and First Null Beam Width … 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.

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. WebThese active antennas can be used for different applications, such as direct-conversion demodulation, Doppler frequency detection and direction finding.

WebJul 30, 2024 · This mode of operation is obtained by raising the circumference to the order of one wavelength (C/λ) and a spacing of approximately λ/4. The radiation pattern is broad and directional along the axial beam producing minor lobes at oblique angles. The above shown is the radiation pattern for an axial mode of radiation in the helical antenna.
