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 ...
متن کاملMutual Coupling Reduction in Patch Antenna Arrays Using Corrugated Structure
Microstrip antennas are widely used in a broad range of military and commercial applications due to its low cost, low profile, easy fabrication and light weight. But this kind of antenna also has some drawbacks. For example, the diffraction of surface waves at the edge of finite grounded substrate decreases the antenna efficiency and degrades the antenna pattern [1]. In the phased array antenna...
متن کاملLimited 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 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 کاملAn Efficient Metamaterial- Inspired Electrically-small Antenna
This article presents an inexpensive, efficient, and electrically-small antenna design that is based on a metamaterial-inspired structure driven by an electrically-small semi-circular loop antenna, which is coaxially-fed through a finite ground plane. The proposed antenna system is linearly scalable over a wide frequency spectrum. The design details and radiation characteristics of the antenna ...
