Advances in reflectarrays and array lenses with electronic beam-forming capabilities are
enabling a host of new possibilities for these high-performance, low-cost antenna …

Resonant cavity antennas (RCAs) are suitable candidates to achieve high-directivity with a
low-cost and easy fabrication process. The stable functionality of the RCAs over different …

We study multiuser communication systems enabled by an unmanned aerial vehicle (UAV)
that is equipped with a directional antenna of adjustable beamwidth. We propose a fly-hover …

In this communication we present a concept of a partially reflective surface (PRS) antenna
capable of independent beam-scanning and beamwidth dynamic control. The beamwidth is …

A novel fixed-frequency electronically steerable Fabry-Pérot Antenna (FPA) with electronic
two-dimensional (2-D)(azimuth and elevation) steering capability is presented. The …

This letter investigates the completion time and energy consumption minimization for
unmanned aerial vehicles (UAVs)-enabled multicasting over a large area. We propose a fly …

Linearly polarized and dual-polarized magneto-electric (ME) dipole antennas with a
dynamic beamwidth control in the H-plane are presented. The design methodology uses …

Ultra-reliable low-latency Vehicle-to-Everything (V2X) communications are needed to meet
the extreme requirements of enhanced driving applications. Millimeter-Wave (24.25-52.6 …

In this paper, a 2.5-D approach has been used to design 2.5-D miniaturized multifunctional
active frequency-selective surfaces (2.5-D MMAFSSs). The unitary element, based on the …

A partially reflective surface (PRS) antenna design enabling 1-bit dynamic beamwidth
control is presented. The antenna operates at X-band and is based on …
