Mutual coupling reduction with a wideband planar decoupling structure for UWB–MIMO antennas

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 ...

Wideband Planar Slot Antennas

Abstract ⎯ In this paper a printed dipole antenna and three slot antennas are designed to operate at 10 GHz for use in radar systems. A parametric study of each antenna and comparison between their radiation properties including return loss, bandwidth, directivity, efficiency and radiation patterns for 6-element linear array are introduced. Slot antennas show wider bandwidth, less coupling and ...

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 Techniques in Microstrip Patch Antennas: a Survey

An important challenge in communication industry is to reduce the total size of devices. Similarly array size reduction has attracted increasing interest in recent years. Placing elements of an antenna array close to each other is certainly one way to reduce the total size of an array antenna. However, one of the factor called mutual coupling depends on inter element separation and relative ori...
