A type of directional antenna used on some types of radar and radio equipment consisting of an array of elemental, single-wire dipole antennas and reflectors. Named for its inventor Japanese electrical engineer Dr. Hidetsugu Yagi (1886-1976).
Linear end-fire antenna, consisting of three or more half-wave elements, one driven, one reflector, and one or more directors, providing very high directivity and gain, formal name: Yagi-Uda array.
Communications: An unidirectional antenna with at least three elements: a reflector, a driven element and at least one director. Also called a Yagi-Uda Array, after Hidetsugu Yagi and Shintaro Uda, who collaborated in developing this antenna type.
An antenna for wireless with a series of antenna elements placed along a metal rod. As a highly directional antenna, yagi antennas are intended to send or receive a propagated radio signal on the same axis as the corresponding antenna on the other end (with line-of-sight visibility between the two whenever possible). While omni-directional antennas are great for short range broadcasts because of their versatility, high gain directional antennas are recommended for most long range wireless video applications.
A highly directional antenna containing parallel antenna elements that reflect and direct the incoming signals to the driven element (the part that is electrically connected to the transmission line).
a moderately high-gain unidirectional antenna
A multiple element parasitic antenna; originated by Yagi-Uda, in Japan; a common VHF and UHF means of achieving high antenna gain in a compact physical size. It is a linear end-fire array consisting of a driven element, a reflector element, and one or more director elements.
A Yagi-Uda Antenna, commonly known simply as a Yagi antenna or Yagi, is a directional antenna consisting of an array of a dipole and additional parasitic elements. The dipole in the array is driven, and another element, slightly longer, operates as a reflector. Other shorter parasitic elements can be added in front of the dipole as directors.
