🔍 Key Concepts

• Relationship between antenna length (aperture) and beam focusing • How directional antennas behave as their physical size increases • Difference between wide beam vs narrow beam coverage on the horizon

💭 Think About

• If you want to concentrate more energy in a specific direction on the horizon, would you use a longer or shorter antenna? Why? • Think about radar or VHF antennas on ships: what kind of antenna produces a sharper, more precise bearing to a target? • How does increasing the effective aperture (size) of any sensor or emitter—like a flashlight reflector or a camera lens—generally affect the width of its beam or field of view?

✅ Before You Answer

• Remember that antenna length is directly tied to directivity (how focused the beam is). • Visualize: for the same power, does a longer antenna spread energy over a larger angle, or squeeze it into a smaller angle? • Eliminate any choice that suggests no relationship between antenna length and horizontal beamwidth, unless you can justify it using antenna theory.

Question 1 of 20

How does antenna length affect the horizontal beamwidth of the transmitted signal?

The longer the antenna the wider the horizontal beamwidth.

The longer the antenna the narrower the horizontal beamwidth.

The horizontal beamwidth is not affected by the antenna length.

None of the above.
