Question 1

Antenna & Wave PropagationAperture & Gain

For an aperture antenna, increasing the effective aperture while wavelength is fixed generally causes gain to?

Correct Answer: A. Increase

Explanation: Gain and effective aperture satisfy Ae=G lambda²/(4pi), so at fixed wavelength larger effective aperture means larger gain.
