Composite materials for Parabolic antenna in Ka band

<H1>Hello,
there is anyone that know where I can take some informations or papers, on composite materials for parabolic antenna relating to satellite applications in Ka Band?

Thanks in advance</H1>

One easy way to find 'papers' is to add the term '.pdf' to a normal Google search.

Precanned search:

Curious - is your satellite application up there in orbit or down here on the ground?

Consumer Ka-band dishes (used for the recent high speed Internet service - example WildBlue) are stamped out of metal just like any normal satellite TV dish (except probably held to tighter tolerances).

Aircraft and such typically use composite dishes and there are some ka-band and higher applications.
