Linear polarization selective screen
First Claim
Patent Images
1. A linear polarization selective screen for interaction with electromagnetic wave energy associated with an antenna and allowing only electromagnetic waves having a desired linear polarization to pass therethrough, said screen comprising:
- frame structure including first and second spaced end portions lying in a common plane;
a plurality of relatively thin conductive flat ribbons supported between said end portions of said frame structure, said ribbons being at substantially the same potential, and the broad surfaces of said ribbons being parallel and orthogonal to said common plane of said frame structure; and
tension means associated with said frame structure and said ribbons for maintaining a predetermined tensional force on each of said ribbons.

Abstract
A polarization selective screen allowing only electromagnetic waves having a desired linear polarization to pass therethrough, the screen includes an array of relatively thin, parallel and evenly spaced conductive flat ribbons supported between end portions of a frame structure, the broad surface of the ribbons being orthogonal to the plane of the screen and being supported and maintained in place under a predetermined tensional force by tension means such as spring-loaded ribbon hangers.
