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 …

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 …

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 …

This paper presents a substrate integrated waveguide (SIW) multibeam slot array operating
at GHz for future 5G mobile terminal applications. The multibeam forming network is realized …

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 …

This letter presents a compact dual-layer 4× 8 Butler matrix (BM) with sidelobe level (SLL)
suppression in substrate-integrated waveguide (SIW) technology. Addressing the excessive …

The design procedure and measured results of a novel Butler matrix are presented in this
paper. This asymmetrical structure provides fairly flexible phase outputs; therefore, the array …

This paper presents a substrate integrated waveguide Butler matrix with a modified hybrid
coupler, operating from 28 to 32 GHz. The modified hybrid coupler is realized by using 90° …

An integrated solution for the development of multilayer antenna modules for fifth-generation
(5G) communications, based on low temperature cofired ceramic (LTCC), is presented. The …
