Dual-Band MIMO Antenna With Compact Self-Decoupled Antenna Pairs for 5G Mobile Applications

IEEE Access, 2019
In this paper, a dual-band four-element multi-input and multi-output (MIMO) antenna system based on compact self-decoupled antenna pairs is proposed for the fifth-generation (5G) operation in mobile terminals.

Performance of multiple-input multiple-output wireless communications systems using distributed antennas

, 2005
In this contribution we propose and investigate a multiple-input multiple-output (MIMO) wireless communications system, where multiple receive antennas are distributed in the area covered by a cellular cell and connected with the base-station (BS).

Comparison of an electrically-small planar antenna array with a conventional monopole array [PDF]

, 2002
A new type of linear array is proposed which utilises annular slot antennas operating in the 'DC' mode. These conformal elements are electrically-small and have wire-monopole-like radiation patterns.

Wideband patch antenna through introducing co‐plane terminal

IET Microwaves, Antennas & Propagation
Wideband operation is a crucial topic in patch structure research. Various wideband methods have been developed for patch antennas. However, some of the key benefits of patch antennas, such as semi‐space radiation and easy fabrication, are degraded.
