Name: Communications: radio wave antennas > Antennas > Antenna components > Refracting means and radio wave energy filters (e.g., lenses and polarizers)
Description: Subject matter including components which transmit therethrough a radio wave which impinges thereon from space and returns the wave to space after it has passed through and which modify the wave in transmission therethrough usually by delaying or accelerating some portions of the wave more than others, as follows: (1) alters the direction of propagation of the wave, as by refraction; (2) brings the wave front to a focus or converts a plane wave front to a spherical wave front or vice versa (3) changes the type of polarization, e.g., converts a plane polarized wave to a circularly polarized wave, or rotates the plane of polarization; (4) filters one or more polarization components (5) filters one or more frequency components.
