Balanced antenna: An antenna is balanced with respect to ground
when both its arms have the same electrical relationship to ground.
Balanced transmission line: A transmission line whose conductors
have voltages of opposite polarity and equal magnitude with
respect to the Earth.
Balun: A device for feeding a balanced load with an unbalanced
line, or vice versa. An acronym for Balanced/Unbalanced. Read more Balun Definition.
Bandwidth: The width of a band of frequencies used for a particular
purpose.
Baud: The number of times per second the carrier signal changes
value. Refer to Definition of Baud.
BAY. Part of an antenna array.
Beam steering: Changing the direction of the main lobe of a radiation pattern. Note: In radio systems, beam steering may be accomplished by switching antenna elements or by
changing the relative phases of the rf signals driving the elements. In optical systems, beam steering may be accomplished by changing the refractive index of the medium through
which the beam is transmitted or by the use of mirrors or lenses.
Beam Width: The angle, in degrees, between the half-power points (-3 dB) of an antenna beam.
Antenna Beam Width
Beverage antenna: A horizontal, long-wire antenna designed for reception and transmission of low-frequency, vertically polarized ground waves.
Biconical Antenna: An antenna consisting of two conical conductors, having a common axis and vertex, and extending in opposite directions.
Bidirectional: In two directions, usually opposite.
Bidirectional array: An array that radiates in opposite directions along the line of maximum radiation.
Blob: Small areas of the atmosphere where temperatures and pressure differences produce conditions suitable for the refraction of radio waves.
Bowtie Antenna: A style of antenna used for UHF reception [TV].
Bowtie Antenna
Braid: An essential part of many fiber-optic cable designs, consisting of a layer of woven yarn. Note: In the case of single-fiber loose-buffered or two-fiber "zip-cord" loose-buffered fiber-optic cables, the braid is situated between the buffer tube and jacket. In the case of cables having multiple buffer tubes, the braid is usually situated between the inner jacket and outer jacket. Loosely, an unwoven parallel bundle of yarn situated around the tight buffer of a single-fiber or two-fiber "zip-cord" fiber-optic cable. Notes: The braid serves to add tensile strength to the cable. The braid may also be anchored to an optical connector or splice organizer assembly to secure the end of the cable. The braid is often of an aramid yarn.
Broadband antenna: An antenna capable of operation over a wide band of frequencies
Broadside antenna: Synonym billboard antenna.
Broadside array: An array in which the direction of maximum radiation is perpendicular to the plane containing the elements.
