This paper presents an approach for designing metasurface antennas using the
characteristic mode analysis method for 5G mm-wave multiple input–multiple output (MIMO) …

A surrogate-assisted defected ground structure (DGS) design is proposed to suppress E-and
H-plane couplings simultaneously in a 2× 2 microstrip antenna array at 2.45 GHz. The DGS …

We propose a coupling-grounded patch (CGP) antenna pair for sharing the same radiator
with the high isolation performance, where the two feeding ports are connected through …

A decoupling structure with polarization rotation (DSPR) property is proposed to reduce the
mutual coupling between co-or cross-polarized antennas. The proposed DSPR generates a …

A novel design concept for bending the electric-field nulls of a single dual-port microstrip
patch antenna (MPA) for colinear polarization decoupling is proposed in this …

Correlations and mutual couplings in antenna arrays lead to performance deterioration of
multiple-input-multiple-output (MIMO) systems. The relation between mutual coupling and …

A simple decoupling structure for a stacked microstrip patch antenna array is proposed. By
loading a shorting C-shaped structure and a square ring, the mutual coupling between …

This article presents a wideband printed-monopole antenna pair with enhanced isolation. A
clear two-step method based on even-mode (EM) and odd-mode (OM) analyses is …

Dielectric resonator antenna (DRA) arrays with enhanced isolation and front-to-back ratio
(FBR) are proposed in this letter. Specifically, each DRA element is mounted on a small and …

The staggered placement of array antenna is a neoteric configuration to improve antenna
isolation. On this basis, how to further effectively reduce the mutual couplings of different …
