Next-generation cellular technologies, commonly referred to as the sixth generation (6G),
are envisioned to support a higher system capacity, better performance, and network …

To support the ever-increasing demand on connectivity and datarates, multiple beam
antennas are identified as a critical technology for the fifth generation (5G), the sixth …

Here, we propose a fully metallic implementation of a Luneburg lens operating at Ka-band
with potential use for 5G communications. The lens is implemented with a parallel plate that …

With the advent of 5G and future trends for communication systems moving to millimeter
wave (MMW) and higher frequencies, antennas will be required to have high gain, wide …

Antennas for future communication systems are required to be highly directive and steerable
to compensate for the high path loss in the millimeter-wave band. In this work, we propose a …

This article summarizes the recently discovered opportunities of geodesic lenses for
producing high-performing antennas for 5G/6G communications. First, we explain the …

The presence of glide symmetries in periodic structures can introduce beneficial
modifications in their electromagnetic properties. The difference between glide and non …

Here, we propose a low-profile polarizing technique integrated in a parallel plate waveguide
(PPW) configuration, compatible with fully metallic geodesic lens antennas. The geodesic …

As a novel and attractive advanced manufacturing technology, three-dimensional (3D)
printing can realize the manufacturing of devices with more sophisticated structures …

We study the wave propagation between two glide-symmetric metallic plates drilled with
periodic rectangular holes. A mode-matching method is proposed in order to derive …
