In this paper, a low-profile, compact, high-gain antenna solution for four-port mm-wave
broadband MIMO communication in a 5G environment is presented. The proposed antenna …

This article presents a 26–40 GHz dual-polarized phased array. For the dual-polarized
phased array antennas, the sources of cross-polarization leakage mainly include the …

In this article, we propose a novel THz-MIMO antenna system for future wireless
applications. The performance of THz systems is prominently influenced by the MIMO …

Millions of passengers use high-speed trains (HSTs) daily, in the world. The roofs of HSTs
can be equipped with a variety of transmitting and receiving antennas to accommodate high …

A novel methodology based on the sectorization of multiple-port cavities with azimuthal
symmetry into sector unit cells is presented to design 5G multiple-input multiple-output …

The integration of microwave and mm-wave antenna is recognized as a promising solution
to ensure backward compatibility while effectively utilizing available space for 5G-enabled …

In practice, the broadband feeding network on the back side of an antenna can have a
nonnegligible effect on the antenna's back radiation due to the feeding network's radiation …

This paper proposes an eight-element dual-band multiple-input multiple-output (MIMO)
antenna that operates in the fifth generation (5G), n78 (3400–3600 MHz), and WLAN (5275 …

In this study, we designed and observed an ultrabroadband absorber and bi-functional
sensor based on a water-based metamaterial. The cavity material of the unit cell was …
