Title:
RADOME WITH A SURFACE VARYING REFRACTION ANGLE FOR PHASED ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/152070
Kind Code:
A1
Abstract:
Radome with a surface varying refraction angle for phased array antennas. The radome comprises an electromagnetic wave active area which consists of a dielectric substrate and two dual-polarized meta-surfaces. The dual-polarized meta-surfaces are made of plurality of periodically arranged metallic meta-atoms with open, rotational symmetric, and non-continuous geometrical patterns. The meta-atoms overlap complementarily between the two sides of the dielectric substrate and are periodically arranged into at least two groups covering a space region the angular radiation pattern of a planar array antenna. The geometric dimensions of the meta- atoms vary within each group so that to form an electromagnetic transmissive phase gradient within that group and different from one group to another. The periodicity Δp of the meta-atoms is between λ/4 and λ//1.3, λ/ being the wavelength of an incident electromagnetic wave from a planar array antenna.
