In this paper, a dual circularly-polarized (CP) multi-beam antenna is proposed for future
vehicular radar applications. The antenna is composed of two pillbox reflector beamforming …

This article presents a fully 3D-printed dielectric planar lens operating in the entire Ka-band
manufactured using additive manufacturing and a relatively low-cost 3D-printer. The lens …

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 …

In this letter, we propose and study a 2-D glide-symmetric dielectric periodic structure. We
demonstrate that glide symmetry broadens the bandwidth of operation and achieves lower …

In this article, a new method to design an ultrawideband beam-steering antenna system is
presented. The system is completely passive and suitable for millimeter-wave applications …

This article presents the design of a flat Luneburg metalens antenna at V-band using gap
waveguide (GW) technology. The metalens consists of a parallel plate waveguide (PPW) …

This article investigates the dispersion properties of metasurfaces with hexagonal lattices,
including potential higher symmetric configurations. We explore the relationships between …

We propose and implement a geodesic half-Maxwell fish-eye (MFE)-lens antenna. The lens
was optimized using an in-house physical optics (PO) code adapted for generalized …

This article delves into the industrial evolution of lens antennas for future millimeter-wave
and sub-THz radio access applications. Here, we address the potential advantages of …

The successful implementation of broadband, ultrathin and highly efficient nanostructured
plasmonic absorbers is difficult to realize. The performance of the nanoscale metamaterial …
