🔍 Key Concepts

• Relationship between antenna gain and directivity (how focused the energy is) • How concentrating energy in one direction affects beamwidth • Basic idea: for a given frequency and antenna size, gain and beamwidth are inversely related

💭 Think About

• If an antenna sends its power over a wider angle, what happens to the intensity in any one direction? How does that relate to gain? • Imagine a searchlight: when you make the beam narrower but keep power the same, what happens to brightness? How does that compare to antenna behavior? • Look at each option and ask: if gain is higher (more focused), should the beam get wider, stay the same, or narrower?

✅ Before You Answer

• Remember that higher gain generally means a more focused (more directional) beam. • Check whether wider beam means energy is more spread out (lower intensity) or more concentrated (higher intensity). • Verify that your choice reflects an inverse relationship between gain and beamwidth, not a direct one.

What happens to the beamwidth of an antenna as the gain is increased? The beamwidth:

Increases geometrically as the gain is increased.

Increases arithmetically as the gain is increased.

Is essentially unaffected by the gain of the antenna.

Decreases as the gain is increased.
