Abstract
A linear-to-circular polarizer includes a meanderline polarizer having a plurality of meanderline conductor patterns, and a gridline polarizer having a plurality of conductors arranged in a grid pattern. The gridline polarizer is spaced apart from the meanderline polarizer by a first prescribed distance and the gridline polarizer is spaced apart from a planar antenna aperture of a planar antenna by a second prescribed distance.
