Ever since the deployment of the first-generation of mobile telecommunications, wireless
communication technology has evolved at a dramatically fast pace over the past four …

With the demanding system requirements for the fifth-generation (5G) wireless
communications and the severe spectrum shortage at conventional cellular frequencies …

Substrate-integrated waveguide (SIW) technology represents an emerging and very
promising candidate for the development of circuits and components operating in the …

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 …

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 work proposes a novel multi-beam leaky-wave pillbox antenna. The antenna system is
based on three main parts: feeding part (integrated horns), quasi-optical system and …

In this paper, a 2-D beamforming phased array using a novel 2-D Nolen matrix network is
presented. The Nolen matrix is a novel antenna feeding network composed of only couplers …

An effective development of a class of low-cost planar antenna arrays having a high
reproducibility is presented for 60-GHz band system applications. The proposed antenna …

This article proposed a new triple-band transmission block metamaterial (MTM) for 5G mm-
wave applications. The peak transmission-blocking attributes are achieved at 27.09 GHz …

A new beam-switching array system, capable of providing four sets of switchable beams, is
proposed and demonstrated. The core building block for fulfilling the design is the phase …
