largura do feixe
1. The angular width of the main lobe of the radiation pattern of an antenna, typically measured between the points where the power is half the maximum (half-power beamwidth or HPBW)
The antenna has a beamwidth of 30 degrees in the horizontal plane.
A antena tem uma largura de feixe de 30 graus no plano horizontal.
2. In radar and telecommunications, the angular separation between the half-power points of the antenna's directional pattern
Narrower beamwidth allows for better target resolution in radar systems.
Uma largura de feixe mais estreita permite melhor resolução de alvo em sistemas de radar.
Beamwidth is a specialized technical term primarily used in engineering, telecommunications, and radar fields. It is typically not translated in Brazilian Portuguese technical documentation, where the English term 'beamwidth' is commonly retained. The term is fundamental in antenna design and signal processing applications.
