The flat parabolic surface antenna with large apertures is provided to realize the performance such as high gain,beam forming and multi-beam.

This paper presented a new-style auto-deploying/stowing scheme of paraboloid antenna.

A calculation method and calculation results that show that a new kind of shaped paraboloid antennas can produce a ringy radiation pattern is presented.

In fact,it is difficult to achieve that for most large paraboloid antennas because of their structural characteristics.

Improved evaluation for calculating shape errors of parabolic antennas;

Finite element analysis of a circular parabolic antenna;

With regard to the properties of focus plane of a parabolic antenna, we proposed a novel receiving method of multi-synchronous communication satellites based on single antenna.

Outfield test analysis of offset-fed parabolic reflector antenna;

Design and analysis of a multi-beam parabolic reflector antenna;

Aiming at engineering application,we analyzed radiation of multi-beam parabolic reflector antenna with conical horn feed source.

In general,the analysis methods of paraboloidal reflector antenna use geometrical-optics and physical-optics.

in this paper,radiation patterns of distorted paraboloid antennas whoes reflector surfaces are defined as discrete measured points and whoes feeds are out of focus are investigated.
