which includes 14*14 reflecting elements and features a fully planar compact configuration …

The design, fabrication, and measured results are presented for a reconligurable reflectarray
antenna based on liquid crystals (LCs) which operates above 100 GHz. The antenna has …

This communication presents a novel systematic design of a high-aperture-efficiency and 2-
D beam-scanning nematic liquid-crystal (LC)-based reflectarray (LCRA) that operates in the …

This article demonstrates an electronically scanned reflectarray antenna based on liquid
crystal (LC). The LC-based reflectarray element was designed as a periodically loading of …

This article describes and validates for the first time the dynamic modeling of liquid crystal
(LC)-based planar multiresonant cells, as well as its use as bias signals synthesis tool to …

In this paper, a fully electronically reconfigurable reflectarray antenna that has 14× 14
reflecting elements and features a higher aperture efficiency was designed, fabricated, and …

A quad-polarization reconfigurable reflectarray (RA) antenna, which can work in horizontal
