Folded unipole antenna — The folded unipole antenna was first devised for broadcast use by the late John H. Mullaney, an American radio broadcast pioneer, and consulting engineer. Designed to solve some difficult problems with existing medium wave (MW) amplitude… … Wikipedia
Monopole antenna — Mast radiator monopole antenna used for broadcasting. AM radio station WARE, Warren, Massachusetts, USA. A monopole antenna is a class of radio antenna consisting of a straight rod shaped conductor, often mounted perpendicularly over some type of … Wikipedia
Antenna measurement — techniques refers to the testing of antennas to ensure that the antenna meets specifications or simply to characterize it. Typical parameters of antennas are gain, radiation pattern, beamwidth, polarization, and impedance.The antenna pattern is… … Wikipedia
Random wire antenna — A random length wire antenna is a type of radio frequency antenna typically chosen more for convenience than any particular design criteria. This antenna sometimes is called the zig zag antenna, as it may be strung back and forth between trees… … Wikipedia
folded dipole antenna — An antenna composed of two parallel, closely spaced dipole antennae connected at their ends, with one fed at its center. The folded dipole antenna is the same size, and has the same radiation pattern, as an ordinary dipole antenna, but the feed… … Aviation dictionary
Dipole antenna — A schematic of a half wave dipole antenna connected to an unbalanced coaxial cable. Better practice is to connect the balanced dipole to the unbalanced line with a balun. A dipole antenna is a radio antenna that can be made of a simple wire, with … Wikipedia
Loop antenna — A shortwave loop antenna A loop antenna is a radio antenna consisting of a loop (or loops) of wire, tubing, or other electrical conductor with its ends connected to a balanced transmission line. Within this physical description there are two very … Wikipedia
Parabolic antenna — A parabolic satellite communications antenna at Erdfunkstelle Raisting, the biggest facility for satellite communication in the world, in Raisting, Bavaria, Germany. It has a Cassegrain type feed. A parabolic antenna is an antenna that uses a… … Wikipedia
Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… … Wikipedia
Patch antenna — A patch antenna is a popular antenna type, which gains its name from the fact that it basically consists of a metal patch suspended over a ground plane. The assembly is usually contained in a plastic radome, which protects the structure from… … Wikipedia
