Multi-beam antennas are critical components in future terrestrial and non-terrestrial wireless
communications networks. The multiple beams produced by these antennas will enable …

Millimeter-wave bands (around 28, 38, 60, and 73 GHz) are anticipated to play a decisive
role in the hosting of future wireless systems. The necessity of smart antennas to adaptively …

A multibeam antenna system fed by a compact Rotman lens is presented in multilayer
substrate integrated waveguide (SIW) technology. The lens is implemented in two layers …

A novel multibeam antenna based on a 4× 4 Butler matrix with sidelobe level (SLL) control is
proposed in the 60-GHz band. The SLL is controlled using a dedicated circuit composed by …

The millimeter-wave band is a very attractive frequency band for the new generations of
mobile cellular networks, ie 5G and 6G, due to its potential to support extremely high data …

technology. The phase shifter is aimed at providing beam-scanning capabilities to …

This article presents a parallel-plate lens beamformer for continuous wide-angle scanning.
The design is based on a compact dual-lens system with extended scanning range and is …

A simple and low-cost single substrate layer Luneburg lens-based beamforming network
(BFN) operating in W-band is proposed. A multibeam antenna is then realized using the …

In this letter, we present a planar half-Luneburg lens antenna based on a glide-symmetric
dielectric structure. The proposed half-Luneburg lens antenna provides a compact …

A novel low-cost, dual-polarized, 2-D leaky wave antenna (LWA) with four beams is
proposed in this article. The proposed 2-D LWA includes a 2-D leaky wave radiation …
