What is the importance of HPBW?

Answer 1

HPBW, or Half-Power Beamwidth, is crucial in antenna design as it defines the angular width of the main lobe where the radiated power is at least half of the maximum. This measurement helps in assessing the directivity and focus of the antenna's radiation pattern, indicating how well it can concentrate energy in a particular direction. A narrower HPBW generally signifies a more focused beam, which can enhance communication range and reduce interference from unwanted signals. Understanding HPBW is essential for optimizing antenna performance in various applications, including telecommunications and radar systems.
