This paper highlights recent developments and challenges on beam steering characteristics
of reconfigurable transmitarray antennas. It introduces the operating principle of beam …

Recently, a reconfigurable intelligent surface (RIS) that provides alternative wireless
propagation paths (by reflecting an electromagnetic wave from a base station in desired …

Several linearly-polarized and circularly-polarized transmit-arrays are designed and
demonstrated in the 60-GHz band. These arrays have a fairly simple structure with three …

We present a new technique for designing wideband, single-layer reflectarray antennas.
The proposed reflectarray exploits a wideband, polarization rotating unit cell that rotates the …

This article presents a 38.5 GHz transmitarray, for the first time, embedded into laminated car
glass, and indoor 5G connectivity enhanced by this transmitarray laminated glass has also …

A new implementation of a beam-steering transmitarray is proposed based on the tiled array
architecture. Each pixel of the transmitarray is manufactured as a standalone unit which can …

Three 400-element circularly polarized discrete lens antennas with different F/D ratios and
main beam directions are studied in the 60-GHz band. They are fabricated with a standard …

A novel ultrathin near-field (NF) 2-bit 24× 24element transmitarray lens working at X-band is
presented in this letter. The aim of this antenna is to focus in a point located in the NF without …

A simple structure of reconfigurable unit cell is proposed for 1-bit transmitarrays in the C-
band. It consists of two square ring patches capacitively coupled to U-shaped microstrip …

Transmitarrays have been shown to be viable architectures for achieving high-directivity
reconfigurable apertures. The existing work on reconfigurable transmitarrays is sparse, with …
