Terms starting with ‘B’
- A range of consecutive frequencies comprised of a band (i.e. the US cellular bandwidth is 72 MHz wide between the frequencies of 824 MHz - 890 MHz) over which an antenna shall perform without the need of any adjustment.
- Beam Antenna
- An antenna which radiates greater power in one or more directions allowing for increased performance on transmit and receive and reduced interference from unwanted sources. <img…
- Beam Diameter
- See also: Beamwidth
- Beam Divergence
- An angular measure of the increase in beam diameter or radius with distance from the optical aperture or antenna aperture from which the electromagnetic beam emerges. The term is relevant only in the "far field", away from any focus of the beam.
- Beam Steering
- Changing the direction of the main lobe of a radiation pattern.
- In an antenna pattern, the beamwidth is the size of the angle between the half-power (-3 dB) points of the main lobe, when referenced to the peak effective radiated power of the main lobe.
- Biconical Antenna
- A broad-bandwidth antenna made of two roughly conical conductive objects, nearly touching at their points. Biconical antennas are broadband dipole antennas, typically exhibiting a bandwidth of 3 octaves or more.
- Billboard Antenna
- An aerial half a wavelength long antenna consisting of two rods connected to a transmission line at the center.
- The axis of maximum gain (maximum radiated power) of a directional antenna.
