Title :
Design of low VSWR axisymmetric subreflector
Abstract :
The design of a low VSWR axisymmetric subreflector using the method of moments is described. To reduce the power reflected back into the waveguide horn the surface of the hyperbolic subreflector is deformed using raised-cosine functions. The method of moments technique is then validated by comparing experimental and theoretical results.
