Efficient beam steerable high-gain antennas enable high-speed data rates over long-
distance networks, including wireless backhaul, satellite communications (SATCOM), and …

The design dilemma of" What will be different between near-field communications (NFC)
and far-field communications (FFC)?" is addressed from four perspectives. 1) From the …

Wireless backhaul offers a more cost-effective, time-efficient, and flexible solution than wired
backhaul to connect the edge-computing cells with the core network. As the amount of …

Bessel beams (BBs) can be generated at microwave frequencies by means of compact,
planar devices based on Fabry–Perot cavity leaky-wave resonators. Most designs are based …

In this communication, we present a theoretical analysis, design, and fabrication of a limited-
diffractive planar Bessel beam launcher, that exhibits a zeroth-order Bessel profile in the …

Resonant Bessel-beam launchers are low-cost, planar, miniaturized devices capable of
focusing electromagnetic radiation in a very efficient way in various frequency ranges, with …

Resonant Bessel-beam launchers have recently gained much attention due to their
capability to radiate focused beams by means of a compact and low-cost devices at …

In this work, we study the use of Bessel-Gauss beam launchers for wireless power transfer
(WPT) applications. The power transfer efficiency between two radiating apertures is …

The generation of focused beams in the millimeter-and submillimeter-wave ranges, with
transverse-electric (TE) polarization, is investigated in the radiative near-field region. The …

Near-field (NF) antennas have been successfully adopted in several wireless applications.
