Alphabetical list of terms

Record 1 2002-10-23

English

Subject field(s)
  • Radio Transmission and Reception
DEF

An array of parallel horizontal coplanar dipoles, generally full-wave, half a wavelength apart in a vertical plane.

OBS

pinetree aerial: term standardized by the International electrotechnical Commission (IEC).

OBS

In Teleglobe's Antenna Theory, "pine-tree antenna" is given as synonymous with "pine-tree array". The IEC suggests that a "pinetee array" consists of two "pinetree aerials"(aerial=antenna in North America), one serving as a reflector for the other.

Key term(s)
  • pinetree antenna

French

Domaine(s)
  • Émission et réception radio
DEF

Réseau d'antennes comprenant des doublets horizontaux, parallèles, superposés dans un plan vertical, généralement espacés d'une demi-longueur d'onde et alimentés en phase en leurs centres par des lignes de transmission.

OBS

rideau de doublets : Terme et première définition normalisés par l'AFNOR; Terme et deuxième définition normalisés par la CEI.

  • Radar, Radio Guidance and Goniometry
DEF

An array of dipole antennas aligned vertically (termed the radiating curtain), behind which and approximately a quarter wavelength away is a parallel array of dipole antennas forming the reflecting curtain.

OBS

pinetree array: term standardized by the International Electrotechnical Commission (IEC).

OBS

In Teleglobe's Antenna Theory, "pine-tree antenna" is given as synonymous with "pine-tree array". The IEC suggests that a "pinetree array" consists of two "pinetree aerials"(aerial=antenna in North America), one serving as a reflector for the other.
