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 double-layer lens consists of a first gradient-index/geodesic profile in an upper
waveguide, partially surrounded by a mirror that reflects the wave into a lower guide where …

A continuous beam-steering solution for circularly polarized (CP) radial-line slot array
(RLSA) antennas is presented and demonstrated with a fabricated prototype. The solution is …

This paper presents an 8× 8-element slot array antenna with single-layered corporate-feed
based on the ridge gap waveguide (RGW) technology in the 60 GHz band. As is well known …

This article proposes a novel all-metal mechanical phase shifter in gap waveguide
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 dual-band shared-aperture variable inclination continuous transverse stub (VICTS)
antenna is designed with good port isolation and a low profile. The operation bands …

This article presents a wideband beam-steering antenna system for high-mobility millimeter-
wave (mm-wave) systems. It can provide both continuous and discrete beam steering in two …

This article presents the exact closed-form solution for a new planar lens, hereinafter
referred to as reflecting Luneburg lens (RLL). The proposed structure consists of two stacked …

A W-band large-scale substrate-integrated waveguide (SIW) cavity-backed slot array for
high-gain applications is presented in this communication. The proposed antenna consists …
