2. Attenuator (electronics) - Wikipedia

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

   Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. In measuring signals, attenuator pads or adapters are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it. Attenuators are also used ...

3. Optical attenuator - Wikipedia

   en.wikipedia.org/wiki/Optical_attenuator

   Built-in variable optical attenuators may be either manually or electrically controlled. A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator". In contrast, an electrically controlled attenuator can provide adaptive power optimization.

   Bonnie Crystal was granted the US patent 7,151,497 Coaxial Antenna System on December 19, 2006, after filing in 2003 for new types of coaxial antennas with reduced size providing efficient broadband, wideband and controlled bandwidths, using radiation by the outside of the coaxial elements. [2]

5. Attenuation - Wikipedia

   en.wikipedia.org/wiki/Attenuation

   There also exist optical attenuators that decrease the signal in a fiber optic cable intentionally. Attenuation of light is also important in physical oceanography . This same effect is an important consideration in weather radar , as raindrops absorb a part of the emitted beam that is more or less significant, depending on the wavelength used.

6. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...
