Abstract:

© 2020 IEEE. This paper presents a unique dielectric-free cell configuration that is useful as a building block to design low-cost transparent phase-gradient metasurfaces required for antenna beam steering using both far-field and near-field methods. Each cell is made of a few thin metal sheets each having an asterisk-shaped slot. A phase variation of 360 degrees is possible with four metal layers, with less than 2 dB drop in amplitude. This is much greater than what is possible with the conventional cross-slot which lacks such a high degree of freedom.
