Mutual Coupling Reduction of DRA for MIMO Applications

Mutual Coupling Reduction Techniques between MIMO Antennas for UWB Applications

The recent research has proved that the Multiple-input-multiple-output (MIMO) systems can substantially increase the channel capacity by employing multiple antennas at both the transmitter and receiver, without increasing either transmitter power or bandwidth. Hence it is very much essential to know all the aspects of MIMO system. Usually, in any MIMO system the antenna design plays a major rol...

Mutual Coupling Reduction Between Flexible MIMO Antennas

In this chapter, a novel μ-negative (MNG) metamaterial structure is proposed to reduce mutual coupling between two printed monopole antennas operating at 2.45 GHz. The unit cell consists of two split ring resonator (SRR) structures bridged at the centre, which mimics a cascaded filter; hence, termed as Bridged Split Ring Resonators (BSRRs). This approach enhances the magnitude and bandwidth of ...

Compact EBG Structures for Reduction of Mutual Coupling in Patch Antenna MIMO Arrays

Electromagnetic band gap (EBG) structures are usually realized by periodic arrangement of dielectric materials. These periodic structures can help in the reduction of mutual coupling in array antennas. In this paper a new arrangement of EBG structures is presented for reducing mutual coupling between patch antenna MIMO arrays. The patch antennas operate at 5.35GHz which is defined for wireless ...

Mutual Coupling Reduction of MIMO Antennas using Parasitic Elements for Wireless Communications

A compact two element MIMO (Multiple Input Multiple Output) system is proposed using H-shape antenna with parasitic elements employing polarization diversity. The proposed MIMO system offers improved bandwidth; return loss, separation between antenna elements and isolation characteristics. The system resonates at 2.36GHz and 5.2 GHz frequencies with VSWR ≥2, which can be used for 4G & WiMAX app...
