DOI: 10.1109/tap.2025.3607274

Abstract: This study presents a reconfigurable folded transmitarray (RFTA) capable of dual-polarization beam scanning in both the azimuth and elevation planes. A wideband fan-cross-shaped (FCS) unit cell which constitutes the reconfigurable transmitarray (RTA), separates the polarization… read more here.

DOI: 10.1109/tcsii.2023.3338372

Abstract: A low-profile folded transmitarray antenna (FTA) with independent amplitude and phase control is proposed for the applications of millimeter-wave (mm-wave) communication. The proposed FTA is composed of three functional parts, i.e., an independent amplitude-phase controlling… read more here.
