Abstract (2. Language):
In this paper, in order to find the optimal dimensions
of the subreflector for minimizing the effects of aperture
obstruction, the complex and nonlinear equation related to the
design of the Cassegrain antenna and feed antenna, which is a
conical corrugated horn antenna, is presented as a singlevariable
equation versus ‘A’, one of the parameters of the
hyperbolic reflector surface. Then this equation is solved using
the Newton-Raphson numerical method with high accuracy
and high speed. At the end of the paper, a design example was
investigated to reveal the above method and the optimal
dimensions of the Cassegrain antenna structure were calculated
using this method.
