Abstract
A process for fabricating an antenna system for near Earth and Deep Space applications includes additively manufacturing an aluminum alloy powder feedstock on a build plate to form a monolithic choke ring horn antenna and a septum polarizer system layer by layer; exposing the monolithic choke ring horn antenna and the septum polarizer system on the build plate to a heat treatment process; coating nickel onto surfaces defining the monolithic choke ring horn antenna and the septum polarizer at a thickness effective to reduce surface roughness; and coating gold onto the nickel coating at a thickness effective to reduce radiofrequency loss when in use.
