|What is antenna beamwidth?|
|Answer:1.Degrees between the half power points (3 dB) of the major lobe of the antenna.|
2.In addition to directivity, the radiation patterns of antennas are also characterized by their beamwidths and sidelobe levels (if applicable).
3.Antenna beamwidth is the peak-to-peak angle overlaying the maximum gain beam of the antenna at which its gain is reduced by 3 dB.
4.Beamwidth = 70λ / D where, λ = Wavelength D = Diameter .
5.The narrower the beam the higher the power density that will be achieved.
