International audienceIn this paper, Artificial Neural Network technique used for the analysis of multi-antenna system is presented. Used in conjunction with a developed Matlab code, this solution allows also to design quickly and accurately a high port to port isolation multi antenna system by giving the different physical parameters of the structure for desired performance set by the user for all application in the band of [1.15-5.825GHz]. Validated in this paper for a two-antenna system isolated by slot, this solution can be generalized to any other type of system

“…A clear distinction should be made between cloaks that can hide an object in free space and the so-called ground-plane cloaks that can be used to hide an object above a boundary [11]. In ground-plane cloaks the complexity of the material parameters is not as demanding as in cloaks operating in free space.…”

“…Another approach is etching an isolating slot between the antenna elements. For example a vertical slot [9], a T-shaped slot [10], or two L-shaped slots [11] have been used. Although these isolating slots reduce the mutual coupling between the antennas, they do not improve their bandwidth.…”

A compact dual-port, multiple input-multiple output (MIMO) antenna array for handheld devices is introduced. The antenna structure consists of two quarter wavelength monopole slots etched on the ground plane of a printed circuit board (PCB) and a meandered slot cut between them. The meandered slot not only reduces the coupling between the two slot antennas, but also improves the bandwidth and efficiency of the array by acting as a radiating parasitic element. Simulated and measured results show that the meandered isolating slot allows the antennas to achieve wider bandwidth, higher efficiency, higher isolation and better diversity performance, compared to other types of isolating slots.

“…The isolation of MIMO antennas by a decoupling network has been proposed in [4]. To achieve better isolation between MIMO antennas, /4 band notched slots have been created on ground plane [5]. In [6] different slots and slits have been combined to realize the quad-band operation in dual-element planar inverted-F antenna.…”

The advent of metamaterials has enabled the researchers to design materials which are non-existent in nature. This exclusive property has opened new horizons for the RF and microwave engineers to customize materials that possess the unique properties of negative permittivity and negative permeability which otherwise cannot be realized using natural materials. When carefully designed, SRR on a substrate exhibit band reject characteristics. These SRR based bandstop filters are extremely beneficial in applications such as multiple input multiple output (MIMO) systems. In this paper two different SRR band stop filters are presented. The designed filters produce isolation responses, satisfying IEEE 802.11a/b/g WLAN band requirements i-e., (2.41 to 2.49 GHz, 5.15 to 5.35 GHz and 5.725 to 5.825 GHz). The first design is a doubly SRR to produce a band reject response from 1.86 GHz -2.65 GHz. The second designed filter is a closed loop SRR with T-shaped strips. It has been designed to provide high reflectivity and wide bandwidth rejection at 5 GHz band i.e., from 5 GHz -5.75 GHz. The simulation of SRR band stop filters has been carried out in CST microwave studio.
