How is the beamwidth of a wireless antenna measured on a plot?
- The beamwidth is determined by finding the weakest point on the plot and following it in either direction until the signal increases by 3 dB.
- The beamwidth is determined by finding the weakest point on the plot and following it in either direction until the signal decreases by 10 dB.
- The beamwidth is determined by finding the strongest point on the plot and following it in either direction until the signal decreases by 3 dB.
- The beamwidth is determined by finding the strongest point on the plot and following it in either direction until the signal decreases by 10 dB.
Explanation: Beamwidth is viewed as a measure of focus for a particular antenna. Beamwidth is determined by finding the strongest point on the plot and following it in either direction until the signal is one-half of the strongest power or 3 dB less.
