Mutual Coupling Reduction Techniques on a Multiband Compact Planar MIMO Antenna

Mutual Coupling Reduction in Patch Antenna Arrays Using a Planar Compact EBG Structure

An important issue in antenna array design is reduction of mutual coupling. In microstrip antennas this reduction can be achieved by using electromagnetic band-gap (EBG) structures. These structures prevent the propagation of surface waves on the substrate of a microstrip antenna array. This paper presents a new configuration of a planar compact electromagnetic bandgap structure to reduce mutua...

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 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 Using Dumbbell Defected Ground Structure for Multiband Microstrip Antenna Array

A novel design of multiband microstrip antenna array with dumbbell shape defected ground structure (DGS) is presented. The DGS is inserted into the ground plane between the two elements of the antenna array in order to suppress mutual coupling. Both simulation and measurement results verified that the DGS improved the radiation properties of the antenna array. Measurement results of the DGS ant...
