A ferrite loopstick antenna, a small loop used for AM reception in a portable radio, consisting of a wire wound around a ferrite core; the most common type of loop antenna today. A loop antenna is a radio antenna consisting of a loop or coil of wire, tubing, or other electrical conductor, that for transmitting is usually fed by a balanced power ...
The antenna used for broadcasting through the 1920s was the T-antenna, which consisted of two masts with loading wires on top, strung between them, requiring twice the construction costs and land area of a single mast. [2] (pp 77–78) In 1924 Stuart Ballantine published two historic papers which led to the development of the single mast antenna.
the upper half of a vertical full-wavelength loop antenna mounted on the ground (not to be confused with the visually similar but electrically different half-square antenna described below, under array antennas, [u] nor to be confused with the halo antenna, described next). The full loop is cut at two opposite points along its perimeter, and ...
The folded unipole antenna is a type of monopole mast radiator antenna used as a transmitting antenna mainly in the medium wave band for AM radio broadcasting stations. It consists of a vertical metal rod or mast mounted over and connected at its base to a grounding system consisting of buried wires.
A patch antenna is a type of antenna with a low profile, usually consisting of a printed circuit board. It consists of a planar rectangular or circular sheet or "patch" of metal, mounted over a larger sheet of metal called a ground plane. It is the original type of microstrip antenna described by Howell in 1972. [1]
Burg transmitter 210 meter mast. The AM transmitter in Burg, near Magdeburg, Germany, is a huge facility for longwave and mediumwave broadcasting. Its most dominant constructions are a 324-metre guyed radio mast and two 210 metre guyed steel tube masts. The 324-metre-high mast is a grounded construction with triangular cross section.
