  12. For multiple ''feelers'' the Anglicised plural, ''antennas'', is used only rarely in scholarly works in the sciences. In other subjects and in less formal settings, ''antennas'' is found with increased frequency.

  13. For multiple ''aerials'' both plural forms are acceptable in scholarly works. The Latinate plural, ''antennae'', is rarer in less formal settings.

  14. 1908 Fessenden|Reginald Fessenden, "Wireless telephony", ''Transactions of the American Institute of Electrical Engineers'', volume 27, issue 1, pages 553 - 629, January 1908.

  15. 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.

  17. 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.
  18. 1914 Lodge|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.

  19. At that time it was giving the full 50,000 volts, as measured by the needle spark-gap between the antennae and earth.

  21. 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.
  22. 1960 Leonard Hatkin, http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=5008284 "The Signal Corps' contribution to the microwave antenna art", ''IRE Transactions on Military Electronics'', volume MIL-4, issue 4, pages 532-536, October 1960.

  23. : (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.

  26. 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.

  28. 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.

  30. 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.
  31. Some make a distinction between an (m) and an (m), 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, (m) is more commonly used in the United States and (m) is more commonly used in the United Kingdom.

  32. For the faculty of intuitive astuteness, the Latinate plural is used most frequently but both forms are found.
