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 …

In this paper, a novel decoupling technique for closely packed patch antennas using near-
field resonator (NFR) above each antenna element is proposed. The decoupling mechanism …

Several solutions are presented to reduce the mutual coupling between two planar inverted-
F antennas (PIFAs) working in close radiocommunication standards and positioned on a …

A novel structure based on complementary split-ring resonators (SRRs) is introduced to
reduce the mutual coupling between two coplanar microstrip antennas that radiate in the …

The enormous growth of wireless data traffic in recent years has made the millimeter-wave
(mm-wave) technology as a good fit for high-speed communication systems. Extensive …

This letter presents the implementation of a pair of parallel coupled-line resonators (PCRs)
for isolation enhancement in planar microstrip patch array antennas. Each PCR consists of …

Multiple-input multiple-output (MIMO) wireless system is a hot research topic in 5th
generation mobile communication technology (5G), which can increase the channel …

A simple decoupling method of using metallic vias to improve the isolation of millimeter-
wave multiple-input-multiple-output (MIMO) dielectric resonator antenna (DRA) elements is …

In this paper, meta-surface superstrates are used to decouple two linear polarized antennas
coupled in H-plane and E-plane, respectively. By properly designing the geometry of the …

This letter presents an efficient technique to reduce the mutual coupling between two 5.2-
GHz probe-fed patch antennas in an array format. Two different designs of folded split-ring …
