NONLINEAR METASURFACE FOR COMPENSATING SCAN LOSS AT DESIGNED ANGLE

摘要

A non-linear meta surface according to an embodiment of the present invention is composed of a plurality of unit cells arranged in two dimensions, and some of the plurality of unit cells are configured to reduce gain loss generated at a specific angle by beam steering of the array antenna. It is characterized by being arranged in a non-linear structure to compensate. According to an embodiment, by arranging the unit cells non-linearly at the edge portion of the meta surface where loss due to beam steering of the array antenna is relatively large, beam steering loss at a specific angle can be compensated to improve the overall antenna gain. have.
