DEVICE FOR TRANSFORMING ELECTROMAGNETIC WAVE POLARIZATION Russian patent published in 2008 - IPC H01Q15/24 H01Q21/06 

FIELD: antenna engineering.

SUBSTANCE: proposed device has radio-transparent insulating layer and helical components forming lattice structure which are equally spaced apart therein. Axes of all helical components are positioned unidirectionally and lie in insulating layer plane; axis and ends of each helical component form plane perpendicular to direction of reflected wave propagation. Each helical component has following characteristics: N_t turns and helix pitch angle α found from formula where α is angle of helix pitch angle; N_t is turn number of helical component. Length of conductor forming helical component equals half the length of electromagnetic wave.

EFFECT: ability of transforming linearly polarized electromagnetic wave into circularly polarized wave irrespective of plane position of incident linearly polarized electromagnetic wave at desired direction of incident wave propagation.
