The next-generation wireless technology that can fulfill such a demand, namely the fifth-
generation (5G) technology, should provide 1000 times larger capacity. Moreover, sixth …

In the last five years or so, there has been a great interest in RF OAM to address the
contradiction between the lack of wireless spectrum resources and the continually growing …

In this letter, a high-efficiency planar reflectarray with a small size of 3.87 λ 0× 3.87 λ 0 is
designed, which can effectively convert arbitrary polarized waves to orbital angular …

A circular polarization (CP) and mode reconfigurable wideband orbital angular momentum
(OAM) patch array antenna is presented. The proposed design is based on a reconfigurable …

In this letter, a 2× 2 low-profile broadband triple-mode orbital angular momentum (OAM)
array antenna is presented, which can be dynamically controlled with electrostatic method …

The vortex wave that carries orbital angular momentum has attracted much attention due to
the fact that it can provide an extra degree of freedom for optical communication, imaging …

Recently, much attention has been paid to beams carrying orbital angular momentum (OAM)
for radio communication, which faces a great challenge of dynamic generation of OAM with …

In this article, we proposed a method for low sidelobe vortex wave synthesis. Using Fourier–
Bessel series expansion, arbitrary radiation pattern function can be synthesized. Fortunately …

A novel three-dimensional printed discrete dielectric lens (DDL) antenna with orbital angular
momentum (OAM) mode reconfigurability operating at 300 GHz is proposed in this article …

In this communication, an orbital angular momentum (OAM) mode-reconfigurable antenna
based on a uniform circular array (UCA) is presented. To realize multiple switchable …
