BEAMWIDTH (Θ)

The beamwidth of a parabolic antenna refers

to the angular span of the main lobe in the

radiation pattern. It represents the coverage

area and angular extent of the antenna's

main beam. A narrower beamwidth indicates

a more focused and directional antenna

allowing the engeri to be focused to a direct

or point to point communication.

BANDWIDTH

The bandwidth of a parabolic antenna refers

to the range of frequencies over which the

antenna can effectively operate. It

represents the frequency range within which

the antenna's performance. The bandwidth of

a parabolic antenna depends on various

factors, including its design, feed system,

and operating frequency. The basic parabolic

reflector itself has an inherently wide

bandwidth due to its geometry and shape.

However, the actual bandwidth of the entire

antenna system is often limited by the

characteristics of the feed element and

associated components.
