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 …

geodesic-lenses are a compelling alternative to traditional planar dielectric lens antennas,
as they are low loss and can be manufactured with a simple mechanical design. However, a …

This paper presents a Luneburg lens and a Luneburg reflector lens along with the
corresponding compact and cost-effective multibeam antennas in the Ka-band. The …

A parallel-plate Luneburg lens (LL) based on all-metal metamaterial is presented in this
article. To achieve the required refractive index distribution of the LL, an all-metal unit cell …

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 …

This letter presents a novel wideband printed circuit board (PCB)-stacked Luneburg lens
antenna with a flared open edge for multibeam scanning application at 5G millimeter-wave …

Antennas in emerging millimeter-wave (mm-wave) applications are often required to have
low losses and produce a steerable directive beam. These properties are achievable with …

In this article, a dual-polarized multibeam antenna is proposed. Two orthogonally polarized
slotted waveguide antennas (SWAs) are cross-placed as the main radiator, which is …

This letter presents a method to realize anisotropic two-dimensional designs with wideband
operation. Glide symmetry has been proven to increase the bandwidth and equivalent …
