Abstract
A radio frequency (RF) polarizer includes a frame having a first side and a second side spaced apart from and opposite the first side, a first polarizer substrate attached to the first side and including a plurality of conductor patterns formed on a surface of the first polarizer substrate, and a second polarizer substrate attached to the second side. The first polarizer substrate and the second polarizer substrate are attached to the first side and the second side, respectively, under tension.
