Record 1 2012-02-15

English

Subject field(s)
  • Telecommunications Transmission
DEF

The ratio, generally expressed in decibels, of the radiation intensity produced by an antenna in a given direction to the radiation intensity that would be obtained if the power accepted by the antenna were radiated equally in all directions.

OBS

a) If no direction is specified, the direction of maximum radiation intensity from the given antenna is implied; b) If the antenna is lossless its absolute gain is equal to its directivity in the same direction.

French

Domaine(s)
  • Transmission (Télécommunications)
DEF

Rapport, généralement exprimé en décibels, de la partie de l'intensité de rayonnement totale d'une antenne dans une direction donnée et correspondant à une polarisation donnée, à l'intensité de rayonnement qui serait obtenue si la totalité de la puissance fournie à l'antenne était rayonnée également dans toutes les directions de l'espace.

Spanish

Campo(s) temático(s)
  • Transmisión (Telecomunicaciones)
DEF

Relación, expresada generalmente en decibelios, entre la intensidad de radiación producida por una antena en una dirección dada y la intensidad de radiación que se obtendría si la totalidad de la potencia suministrada a la antena fuera radiada del mismo modo en todas las direcciones del espacio.

OBS

Si no hay dirección específica, la dirección de la máxima intensidad de radiación está implícita; Si se trata de una antena sin pérdidas, su ganancia absoluta es igual a su directividad en las misma dirección.

DEF

ratio, generally expressed in decibels, of the radiation intensity produced by an antenna in a given direction to the radiation intensity that would be obtained if the power accepted by the antenna were radiated equally in all directions [IEC 50 (712):1992, 712-02-43]

OBS

If no direction is specified, the direction of maximum radiation intensity from the given antenna is implied. [IEC 50 (712):1992, 712-02-43]

OBS

If the antenna is lossless its absolute gain is equal to its directivity in the same direction. [IEC 50 (712):1992, 712-02-43]

OBS

absolute gain; isotropic gain: terms and definition standardized by ISO/IEC [ISO/IEC 19762-4:2008].
