This two-part article presents a review of different techniques of mutual coupling (MC)
reduction. MC is a major issue when an array of antennas is densely packed. When the …

In this article, a novel slot-array defected ground structure (DGS) for decoupling microstrip
antenna array is proposed. The slot-array DGS is etched surrounding each antenna element …

This paper presents a study of a planar antenna-array inspired by the metamaterial concept
where the resonant elements have sub-wavelength dimensions for application in microwave …

A self-decoupling method for the multiinput multioutput (MIMO) antenna array is
investigated. This method is based on the specific characteristic mode (CM) of the ground …

A novel decoupling method is investigated for the multi-input multi-output (MIMO) microstrip
patch antenna (MPA) array. This method makes use of the TM 10 and TM 02 modes, which …

This paper proposes a hybrid decoupling method based on a novel electromagnetic
bandgap (EBG) structure and hair-pin shaped defected ground structure (DGS) to obtain …

In this paper, a ε-negative metasurface superstrate is proposed for mutual coupling
reduction of large antenna arrays. Unlike the previous decoupling metasurface works that …

A simple decoupling method of using specific higher-order modes to improve the isolation of
dielectric resonator antenna (DRA) elements is investigated. The higher-order modes have …

This paper investigates a simple method based on the metasurface concept to suppress the
mutual-coupling between the radiation parts of a 2× 2 antenna-arrays. The array-antennas …

A circularly polarized (CP) multiple-input-multiple-output (MIMO) antenna is investigated.
This MIMO antenna consists of two identical dielectric resonator antennas (DRAs), which …
