2. Waveguide flange - Wikipedia

   en.wikipedia.org/wiki/Waveguide_flange

   So for example UBR220 is a square plain cover flange for R220 waveguide (that is, for WG20, WR42), PDR84 is a rectangular gasket flange for R84 waveguide (WG15, WR112) and CAR70 is a round choke flange for R70 waveguide (WG14, WR137).

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 ...

   en.wikipedia.org/wiki/File:Waveguide-choke...

   English: E-plane cross-section of connected choke and gasket/cover waveguide flanges. These are the flanges in the photo Waveguide-choke-flange-UG-1666-U.jpg. In the cross-section, the gap between the flange faces has been exaggerated by a factor of 4 to make it clearly visible. Legend: a. waveguide tubing socket-mounted into... b. choke flange ...

5. Waveguide - Wikipedia

   en.wikipedia.org/wiki/Waveguide

   An example of a waveguide: A section of flexible waveguide used for RADAR that has a flange. Electric field Ex component of the TE31 mode inside an x-band hollow metal waveguide. A waveguide is a structure that guides waves by restricting the transmission of energy to one direction.

7. Substrate-integrated waveguide - Wikipedia

   en.wikipedia.org/wiki/Substrate-integrated_waveguide

   Each mode appears above a precise cut-off frequency determined by the waveguide dimensions and the filling medium. For TM modes, decreasing the waveguide thickness (usually denoted as ) increases the cut-off frequency with /. In the case of SIW, the thickness is so low that the cut-off frequency of TM modes is much higher than the dominant mode.

8. Horn antenna - Wikipedia

   en.wikipedia.org/wiki/Horn_antenna

   A horn antenna is used to transmit radio waves from a waveguide (a metal pipe used to carry radio waves) out into space, or collect radio waves into a waveguide for reception. It typically consists of a short length of rectangular or cylindrical metal tube (the waveguide), closed at one end, flaring into an open-ended conical or pyramidal ...

9. Slot antenna - Wikipedia

   en.wikipedia.org/wiki/Slot_antenna

   Slotted array UHF television broadcasting antenna. As shown by H. G. Booker in 1946, from Babinet's principle in optics a slot in a metal plate or waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot, with the exception that the electric field and magnetic field directions are interchanged; the antenna is a magnetic dipole instead of an ...
