Limited Size MIMO Antenna Systems and Mutual Coupling Challenge
The wireless communication high data rate is achievable by installing more than one antenna in receiver and transmitter terminals as MIMO antenna. In order to obtain the MIMO gain (Envelope Correlation Coefficient (ECC) ≤ 0.5), the antenna elements must be at least separated by a distance of 0.5λ (λ is the operating wavelength of 0.7~3.8 GHz which is the frequency range of most of the current w...
متن کاملImpact of Mutual Coupling on Adaptive Switching Between MIMO Transmission Strategies and Antenna Configurations
Adaptive switching between multiple-input multiple-output (MIMO) transmission strategies like diversity and spatialmultiplexing is a flexible approach to respond to channel variations. It is desirable to obtain accurate estimates of the switching points between these transmission schemes to realize the capacity gains made possible by adaptive switching. In this paper, it is shown that the accur...
متن کاملMutual 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 ...
متن کاملCompact 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 ...
متن کاملInvestigations into Capacity of MIMO Ad Hoc Network Including Effects of Antenna Mutual Coupling
This paper reports on investigations into capacity of ad hoc network whose nodes are equipped with multiple element antennas (MEAs). The investigation of this multi-user Multiple Input Multiple Output (MIMO) system takes into account mutual coupling (MC) in addition to spatial correlation that is present in array antennas. A closed-form expression for an upper bound of mutual information (capac...
