An Ultralow-Profile Folded Transmitarray Antenna With Both-Sides Beam Regulate for K-Band Circularly Polarized OAM Waves

IEEE Antennas and Wireless Propagation Letters
An ultralow-profile, high-gain folded transmitarray antenna (FTA) for generating the orbital angular momentum (OAM) is proposed in this letter. The folded antenna consists of a receiver/transmitter (R/T) structure metasurface and a metal plate reflector.

Design and Implementation of a Reconfigurable Transmitarray Employing Varactor-Tuned Huygens Elements for Dynamic Beam Shaping

IEEE Antennas and Wireless Propagation Letters
Most conventional reconfigurable transmitarrays rely on multilayer frequency-selective surfaces and PIN diodes, limiting transmittance and multibit modulation, which constrains beamforming accuracy and gain enhancement. In this letter, we propose a phase-
