[fɑːr-fiːld ˈpætərn]
nounpl: far-field patterns
padrão de campo distante
1. The radiation pattern of an antenna or electromagnetic source as observed at a distance much greater than the wavelength of the radiation, where the wavefront appears planar rather than spherical
The far-field pattern of the antenna was measured at a distance of 100 meters from the transmitter.
O padrão de campo distante da antena foi medido a uma distância de 100 metros do transmissor.
2. In acoustics or optics, the radiation characteristics of a source in the region where the wave front can be approximated as a plane wave
Engineers analyzed the far-field pattern to understand the speaker's directional output in large venues.
Os engenheiros analisaram o padrão de campo distante para entender a saída direcional do alto-falante em locais grandes.
This is a specialized technical term primarily used in electrical engineering, telecommunications, and physics. It is standard terminology in both American and Brazilian technical contexts, with little regional variation. The term is essential in antenna design, radar engineering, and wireless communication systems. In academic and industrial settings in both countries, the English term is often used interchangeably with its Portuguese equivalent.
