A large-scale reconfigurable reflect-array antenna (RRA) with 2-bit phase resolution is reported here at the Ka-band. The unit cell is designed based on a segmented resonator with end folding, which ...

This paper presents a 3D metal-only waveguide-based phoenix cell. The proposed cell uses open-ended waveguides, which allow a portion of the incident wave to pass through the phoenix cell. It thus has ...
