Abstract EN
This research proposes using optical physics method to determine the parameters of a single reflector parabolic antenna in the near field region, at the image plane, and along the focal axis.
The study was carried out when the antenna is focused to the far field region, and at a specific point in near field region.
The scanning parameters of the antenna were studied when the antenna is focused to the near field.
The numerical simulation was carried out by using Delphi code.
It showed that, the field amplitude, with ripple, decreased when the test point moved out from the antenna aperture.
We found that the points of maximum field intensity on the focal axis of the antenna focused in near region were not the focusing points.
It also showed that during the scanning, the increase in the width of the main lobe and the level of side lobes at the picture plane was less than it in the far region.
