From Latin antenna, antemna ("yard, sailyard; pole"). First used in this sense as a Latin word in the 15th century and as an English word by the end of the 17th century.
- (key): /æn't?n.?/, /?n't?n.?/
- Rhymes: -?n?
antenna (plural antennae or antennas)
- A feeler organ on the head of an insect, crab, or other animal. [from 17th c.]
- An apparatus to receive or transmit electromagnetic waves and convert respectively to or from an electrical signal.
- (figuratively) The faculty of intuitive astuteness.

- Most nurses believe they are born with an antenna of sorts, which is able to guide them through clinical practice and help them determine what is right and what is not...

- Obama is astute. He approaches things with the help of a sensitive antenna.
- (biochemistry) A fragment of an oligosaccharide
- (nautical) The spar to which a lateen sail is attached, which is then hoisted up the mast.

- 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.

- The basis of these relationships lies in the olfactory chemoreceptors of insect antennas...
- 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.
- For multiple aerials both plural forms are acceptable in scholarly works. The Latinate plural, antennae, is rarer in less formal settings.

- 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.

- 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.

- 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.

- 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.

- 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.
- 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.
- For the faculty of intuitive astuteness, the Latinate plural is used most frequently but both forms are found.
- 2006 Kelly Pyrek, Forensic Nursing, page 514, ->ISBN.
- ...they get these fully formed antennas. With them they get this amazing sense of intuition, a gut feeling about when something might be wrong.
