This is a review article discussing the latest developments in beam-steering antennas at
millimeter-wave frequencies for Beyond-5G and 6 G networks. This article classifies all the …

A novel design for a beam-switching antenna using active cylindrical slot frequency
selective surface (ACSFSS) is presented. The antenna system is composed of an …

Recent advances in wireless sensing and communications have resulted in the need for
antennas capable of high-directivity reconfigurable beamforming. Transmitarrays have been …

This paper presents a study on reconfigurable transmit-array (TA) antennas based on
multilayer tunable elements. The proposed configuration can be referred to as a multilayer …

At frequencies below 2 GHz, conventional microwave absorbers are limited in application by
their thickness or narrow absorption bandwidth. In this paper, we propose and fabricate an …

A new three-dimensional (3-D) tunable bandpass frequency selective structure (FSS) with
wide tuning range is presented. The tunable FSS consists of a periodic array of printed …

In this communication, we experimentally demonstrate a frequency-and beam-
reconfigurable lens antenna based on an active second-order bandpass frequency …

A wideband switchable frequency selective surfaces (FSS) absorber/reflector for C-band (4–
8 GHz) application of smart stealth system is presented. This switchable FSS has novel …

A novel tunable frequency selective surface (FSS) with dual-degrees of freedom (DOF) is
presented, and firstly applied to broadband absorber. Based on a simple prototype unit cell …
