Question

An antenna’s beamwidth is measured ________

(a) from +90° to -90°

(b) between half power points

(c) between the minor side lobes

(d) between the major side lobes

This question was addressed to me in my homework.

I would like to ask this question from Synchronous TDM topic in section Multiplexing & Sampling of Bandpass Signal of Analog Communications

Answer 1

Right answer is (b) between half power points

The best I can explain: The angle between the half power points of the main lobe with respect to the peak effective radiated power is called half power beamwidth. It is generally measured between half power points.
