چکیده
This paper presents a compact, uni-planer wide band Multiple-Input-Multiple-Output (MIMO) antenna. The designed antenna array has compact size of (26mm x 31mm) covering frequency from 3.1GHz - 11GHz. A partial ground plane shared by two radiating patches is used. stub and single column Electromagnetic Bandgap (EBG) structure in between the results very low mutual coupling proposed MIMO-antenna was evaluated through different performance metric indicators like channel capacity loss, far-field radiation pattern, S-parameters, envelope correlation coefficient, peak gain, diversity-gain efficiency. Our MIMO high isolation amongst antennas ( $\text{S}_{21} < -25$ dB), Diversity-Gain (DG notation="LaTeX">$>9.995$ Envelope Co-relation Coefficient (ECC < 0.001) Channel-Capacity-Loss (CCL 0.1bits/s/Hz). said an average efficiency 85.5% gain (5.67dB) within ultra-wideband (UWB) spectrum. 0.8mm thick FR-4 substrate used to fabricate tested anechoic chamber. measured closely match with simulated results.

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 ...
متن کاملMutual 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...
متن کاملMeandered UC-EBG structure for a reduction of the mutual coupling in a patch antenna array
A meandered uniplanar compact electromagnetic bandgap structure is proposed. Meandered microstrip lines between adjacent cells are used to increase the equivalent inductance. As a result, the dimension of the proposed EBG structure is more compact and its frequency band-gap is wider than that of the conventional uniplanar EBG structure. Two patch arrays with and without an EBG structure were de...
متن کاملDesign and Implementation of a Compact Super-Wideband Printed Antipodal Antenna Using Fractal Elements
A compact printed fractal antipodal bow-tie antenna is designed and implemented to simultaneously cover the operations in the C, X, and Ku-bands. It is demonstrated that by addition of small fractal elements at the sides of hexagonal arms of the bow-tie, a wide operating frequency range of 3.3 to 19.1 GHz can be covered while antenna size is only 30×34×1.2 mm3. In order to match the antenna to ...
متن کاملDesign of a Compact Wideband Mimo Antenna for Mobile Terminals
A new broadband multiple-input multiple-output (MIMO) antenna with good isolation and compact size is proposed. The proposed antenna consists of two G-shaped elements in the upper layer and two inverted L protrude branches and a T slot etched in ground which is used to reduce the mutual coupling. This planar antenna has a bandwidth of 100% with |S11| ≤ −10 dB from 2.26 to 6.78GHz. The value of ...
