“…Besides these ways of influence, to the antennas' operation, the incorporation of EBGs, of mushroom or of other type in antenna arrays, can reduce significantly the isolation among their element reducing their electromagnetic mutual coupling. This result is very useful at MIMO antennas systems as it contributes to the reduction of correlation coefficients among their elements, thus enhancing the MIMO procedure ( [24][25][26][27][28]). In the present work, the performance of the prototype of Figure 7 is presented via Figures 8-11.…”

In this paper, a novel transmission strategy for Mutliple Input Multiple Output Wideband Code Division Multiple Access (MIMO-WCDMA) orientations operating in frequency-selective fading environments is investigated, in terms of overall algorithmic complexity reduction. To this end, Principal Component Analysis (PCA) is employed on the received data matrix, in order to define the significant terms that are taken into account during transmission matrix formulation. According to the presented results, feedback information of only the primary eigenvector of the corresponding covariance matrix of the received data matrix is required, in order to maintain the mean Bit Error Rate (BER) at acceptable levels. In particular, a complexity reduction of up to 10% can be achieved, when comparing BER values derived by the selection of all components of the received covariance matrix during transmission matrix formulation, and the corresponding BER when selecting half of the components. This reduction is maintained to 10%, when considering a realistic four-element antenna design; however, in this case mean BER inaccuracy is further reduced to 1%.

“…However, the proposed antennas in References still have low isolation between the elements. Also, the EBG structures have been employed in the antennas for coupling reduction . For instance, an EBG type isolator is used on the top of the substrate between the two antenna elements in Reference to reduce the mutual coupling.…”

“…In Reference , a combination of EBG and split ring resonator (SRR) structures has been utilized to suppress mutual coupling. In Reference , an EBG‐backed antenna is designed in which the isolation more than 20 dB is observed due to radiating in opposite directions. It is worth noting that the EBG structures have also been used to reduce the size of antennas.…”

This article proposes a compact multiple-input multiple-output (MIMO) antenna with the electromagnetic band gap (EBG) structures for mobile terminals. The proposed MIMO antenna is composed of two radiation patches in which diagonal and folded microstrip lines are utilized to control the frequency bands. The radiation patch, one EBG structure and a rectangular-shaped ground plane are etched on both sides of the antenna. The EBG structures have been employed for reducing the mutual coupling between the antenna elements. As a result of the effect of these structures, the mutual coupling between the two elements is reduced by less than −30 dB. The proposed antenna is implemented on an FR4 substrate with dimensions 20 × 10 × 1 mm 3 . According to measured results, frequency ranges of 2.2 to 3.6 GHz and 5.1 to 5.9 GHz with S 11 < −10 dB and also 3.7 to 5 GHz and 8 to 12 GHz with S 22 < −10 dB have been obtained. Moreover, measured S 12 and S 21 with values of less than −30 dB for both Ports have been realized. Additionally, the envelope correlation and radiation efficiency of the purposed antenna are less than 0.09 and more than 82%, respectively. K E Y W O R D S EBG, LTE, MIMO antenna, WLAN

“…Therefore, reducing the mutual coupling between antenna elements is essential for better performance of MIMO systems. Several works have been carried out to reduce the mutual coupling effect between antenna elements in MIMO systems such as using electromagnetic band gap structures [25]. Also, using defected ground structures (DGSs) etched in different shapes in the ground plane has been employed [26], [27].…”

A design of a compact size mu-negative half mode composite right left handed metamaterial antenna, using only series capacitive loading, for MIMO application is presented. The proposed configuration is simple as it is realized using via free configuration. The MIMO antenna is formed using two antenna elements designed to operate at 5.8 GHz for wireless applications. The overall MIMO antenna size is only 2.6 × 2.6 cm 2 with in-between separation 1.8 mm (0.034  0). Moreover, the ports mutual coupling reduction between the two antenna elements, achieved without using extra structure, is lower than-20 dB. Compared to conventional two microstrip patch MIMO antennas, our proposed configuration has more than 50% size reduction and 9 dB enhancement in the mutual coupling for the same separation. The antenna design principles, full wave simulations, experimental measurements are introduced with good agreement. Finally, MIMO parameters are extracted and discussed.
