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 (FNBW).
23 mar 2023 · Antenna beamwidth is the angular span of the main lobe of the antenna radiation pattern, which is the region of the pattern where most of the power is radiated.
In addition to directivity, the radiation patterns of antennas are also characterized by their beamwidths and sidelobe levels (if applicable). These concepts can be easily illustrated. Consider the radiation pattern given by:
The beamwidth of an antenna is the angle between the directions on either side of boresight which is half of its maximum gain. From: Computer Communications, 2020
Antenna Gain is a measure of power radiated in a particular direction (typically the peak direction of radiation). An antenna's radiation pattern in the far field is often characterized by it's beamwidth and sidelobe levels. This introduction to antenas illustrates this with an example.
Section 3.1 characterizes these general transmitting and receiving properties of antennas, which are derived in subsequent sections. Most antennas reversibly link radiation fields to currents flowing in wires at frequencies ranging from sub-audio through the far-infrared region.
