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 …

Quasi-optical beamformers provide attractive properties for antenna applications at
millimeter-wave (mm-wave) frequencies. Antennas implemented with these beamformers …

This article describes a detailed procedure that allows for a time-efficient design of fully
metallic geodesic H-plane horn antennas using an in-house ray-tracing method together …

The millimeter-wave (mmWave) and sub-terahertz (sub-THz) bands have received much
attention in recent years for wireless communication and high-resolution imaging radar …

Fully metallic geodesic lens antennas are popular for millimeter-wave band applications due
to their simplicity, robustness, and low loss. Here, we report the experimental results of a …

This article presents a fully metallic waveguide-based multibeam antenna operating at the
band from 410 to 480 GHz. The multibeam function is achieved based on the sliding …

We present a dual-polarized lens antenna for point-to-multipoint communications at sub-
THz. The lens is constructed by a doubly-curved parallel plate following a geodesic lens …

In this letter, a multibeam leaky-wave antenna (LWA) based on a modified Luneburg lens
(LL) beamforming network is proposed. The antenna performs a simple structure and low …

A novel Risley prism (RP) integrated with phase-correcting dielectric lens (PCDLs) is
designed and demonstrated at V-band (50–75 GHz) for 2-D beam-steering performance …

A double-layer lens consists of a pair of rotationally symmetric index profiles or geodesic
lens shapes connected by a reflecting mirror partially covering their common periphery …
