This paper presents a thorough review of transmitarray devices particularly aiming antenna
beamsteering, gathering some of the most relevant solutions published by the scientific …

This letter presents the design and results of low-loss discrete dielectric flat reflectarray and
lens for E-band. Using two different kinds of feed, 3-D-pyramidal (wideband) horn and 2× 2 …

Having studied the transmitarray antennas, it is found that the cells depending on their
location on the antenna aperture should have a specific slope in the transmission phase …

The radiation characteristics of the dielectric resonator antennas (DRA) is enhanced using
different types of solid and discrete dielectric lenses. One of these approaches is by loading …

Deploying a massive number of antennas at the base station side can boost the cellular
system performance dramatically. This however involves significant additional radio …

In this paper, the design of single-focused and multi-focused transmitarray antennas in the
near-field (NF) or/and far-field (FF) applications are proposed. A unit-cell element consists of …

A compact 7× 7 flat lens antenna design for X-band applications is presented in this paper. A
new design with aperture-coupled E-shaped patch elements at 10 GHz is simulated and …

Multi-function compact graphene lens antenna in terahertz (THz) band has been
investigated. The array function is switched between two states, reflectarray and/or …

Bi-function Compact graphene lens antenna in terahertz (THz) band has been investigated.
The array function is switched between two status, reflectarray and/or transmitarray. The …

Conventional lenses that have convex, concave, hyperboloid or spherical 3D shape are
difficult to machine and a bit heavy with some complexity in integrating them with other …
