2. Waveguide - Wikipedia

   en.wikipedia.org/wiki/Waveguide

   A waveguide is a structure that guides waves by restricting the transmission of energy to ... non-waveguide) such as coaxial conductors since TEM does not have a ...

3. Waveguide (radio frequency) - Wikipedia

   en.wikipedia.org/wiki/Waveguide_(radio_frequency)

   In radio-frequency engineering and communications engineering, a waveguide is a hollow metal pipe used to carry radio waves. [1] This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave transmitters and receivers to their antennas, in equipment such as microwave ovens, radar sets, satellite communications, and microwave ...

4. Transmission line - Wikipedia

   en.wikipedia.org/wiki/Transmission_line

   Coaxial lines confine virtually all of the electromagnetic wave to the area inside the cable. ... A coplanar waveguide consists of a center strip and two adjacent ...

5. Antenna feed - Wikipedia

   en.wikipedia.org/wiki/Antenna_feed

   The most widely used types of feed line are coaxial cable, twin-lead, ladder line, and at microwave frequencies, waveguide. Particularly with a transmitting antenna, the feed line is a critical component that must be adjusted to work correctly with the antenna and transmitter.

6. Horn antenna - Wikipedia

   en.wikipedia.org/wiki/Horn_antenna

   The radio waves are usually introduced into the waveguide by a coaxial cable attached to the side, with the central conductor projecting into the waveguide to form a quarter-wave monopole antenna. The waves then radiate out the horn end in a narrow beam.

7. Stub (electronics) - Wikipedia

   en.wikipedia.org/wiki/Stub_(electronics)

   Stubs can be constructed with any type of transmission line: parallel conductor line (where they are called Lecher lines), coaxial cable, stripline, waveguide, and dielectric waveguide. Stub circuits can be designed using a Smith chart, a graphical tool which can determine what length line to use to obtain a desired reactance.
