Usage notes[edit]

  1. For multiple feelers the Anglicised plural, antennas, is used only rarely in scholarly works in the life sciences. In other subjects and in less formal settings, antennas is found with increased frequency. quotations ▼
    • 2006 Timothy Duane Schowalter, Insect Ecology: An Ecosystem Approach, page 22 →ISBN.
      The overall shape of most insect antennae is elongate and cylindrical, although elaborations into plumose, lamellate, or pectinate forms have arisen many times in different insect lineages.
    • 2009 Dan Brown, Deception Point, page 24, →ISBN.
      He put his fingers over his head like two antennas, crossed his eyes, and waggled his tongue like some kind of insect.
    • In the same work, Brown uses antennae to refer to both aerials and feelers during more technical descriptions.
    • 2010 Craig S. Charron, Daliel J. Cantliffe, "Volatile emissions from plants", Horticultural Reviews, pages 43-72 →ISBN.
      The basis of these relationships lies in the olfactory chemoreceptors of insect antennas...
  2. For multiple aerials both plural forms are acceptable in scholarly works. The Latinate plural, antennae, is rarer in less formal settings. quotations ▼
    • 1908 Reginald Fessenden, "Wireless telephony", Transactions of the American Institute of Electrical Engineers, volume 27, issue 1, pages 553 - 629, January 1908.
      From 1898 to 1900 numerous experiments were made on antennae of large capacity and it was found that instead of using sheets of solid metal or wire netting, single wires could be placed at a considerable fraction of the wave-length apart and yet give practically the same capacity effect as if the space between them were filled with solid conductors.
    • 1913 Mihajlo Idvorski Pupin, "A discussion on experimental tests of the radiation law for radio oscillators", Proceedings of the Institute of Radio Engineers, volume 1, issue 1, pages 3-10, January 1913.
      When we come to the complicated forms of antennae which we use in practice to-day, it becomes excessively difficult to work out the theory mathematically.
    • 1914 Oliver Lodge, "The fifth Kelvin Lecture: the electrification of the atmosphere, natural and artificial", Journal of the Institution of Electrical Engineers, volume 52, issue 229, pages 333-352.
      At that time it was giving the full 50,000 volts, as measured by the needle spark-gap between the antennae and earth.
    • 1936 Edwin Howard Armstrong, "A method of reducing disturbances in radio signaling by a system of frequency modulation", Proceedings of the Institute of Radio Engineers, volume 24, issue 5, pages 689-740, May 1936.
      If the distance between stations is such that the signal strength varies appreciably with time then the directivity of the receiving antennas must be greater than two to one.

    • In this work Hatkin uses antennas to refer to both aerials and insects.
      ...the waggling of the signal flags...was somewhat reminiscent of the vibrations of the insect's antennas...
      Indeed, many microwave antennas were more reminiscent of optical devices than anything resembling standard radio frequency equipment.

      Bellamy found himself squinting into the glow of what appeared to be some kind of futuristic laptop with a handheld phone receiver, two antennae, and a double keyboard.

      Based on results from the dielectric probe experiment, a prototype system was developed to measure microwave attenuation and phase delay between two antennae in order to detect fungal decay in wood at equilibrium moisture content.

      Contrary to RF antennae, the length of such nanoantennae is shorter than half the operating wavelength for fundamental mode and this happens due to excitation of surface plasmons in the case of latter.
    • 2012 Y. Li, A. Nosratinia, "Capacity limits of multiuser multiantenna cognitive networks", IEEE Transactions on Information Theory, preprint, page 1, March 2012.
      For simplicity of exposition, primary and secondary users are assumed initially to have one antenna, however, as shown in the sequel, most of the results can be directly extended to a scenario where each user has multiple antennas.
  3. Some make a distinction between an antenna and an aerial, with the former used to indicate a rigid structure for radio reception or transmission, and the latter consisting of a wire strung in the air. For those who do not make a distinction, antenna is more commonly used in the United States and aerial is more commonly used in the United Kingdom.
  4. For the faculty of intuitive astuteness, the Latinate plural is used most frequently but both forms are found. quotations ▼


  • (Feeler organ on the head of an insect): feeler
  • (Device to receive or transmit radio-frequency signal): aerial
