"Can you explain the integration method to show
the result?"
The radiation intensity of an aperture antenna, mounted on an infinite ground plane
with perpendicular to the aperture, is rotationally symmetric (not a function of 4),
and it is given by
U =
π sin
Find the approximate directivity (dimensionless and in dB) using
(a) numerical integration. Use the DIRECTIVITY computer program at the end of this
chapter.
