“…The proposed methods for reducing mutual coupling included employing a simple microstrip patch element in between the antennas [6], using parasitic coupling elements between the radiators [7,8], connecting the elements employing a neutralization line [9,10], introducing resonators between the antenna elements [11], placing the antenna elements in an orthogonal configuration [12,13] and metamaterial-based antennas [14]. Alternatively, Electromagnetic Band Gap (EBG) cells [15] and partially extended ground [PEG] plane [16] may be used to eliminate coupling. However, designing the radiating elements as well as parasitic structures, neutralization line, EBG cells, PEG plane, and metamaterial structures requires considerable additional efforts.…”

Abstract-This paper presents a new design approach for compact orthogonal broadband printed multiple-input multiple-output (MIMO) antennas based on a coplanar waveguide (CPW)-fed hexagonalring monopole antenna (HRMA) element. The design procedure of the basic radiating element is initiated from a stripline (SL)-fed circular monopole antenna (CMA). Then various antennas involved in the design evolution process are introduced to attain a compact CPW-fed HRMA. This basic antenna element has a compact size of 13 × 10 mm 2 , 50% smaller than SL-fed CMA, and a prototype of this antenna is built and tested. Based on HRMA element, compact two-and four-element MIMO antenna systems are designed, fabricated and experimentally demonstrated for 5-GHz ISM band operation. The MIMO antenna systems use orthogonally configured of identical closely spaced HRMA elements, with CPW-fed printed on one side of the substrate to achieve good isolation. Design simulation is carried out with the aid of Computer Simulation Technology Microwave Studio (CST MWS) and confirmed with High Frequency Structure Simulator (HFSS). The experimental results are in close agreement with the simulated ones, which validates the design principle. Based on experimental results, the two MIMO antenna systems have an impedance bandwidth of more than 2 GHz, good isolation of less than 15 dB, and a low envelope correlation coefficient of better than −26 dB across the frequency band of (4-6 GHz), which are suitable for 5-GHz MIMO applications.

“…WLAN and WiMax bands were achieved by using slotted ground structure and metamaterial rectangular split ring resonator. Many MIMO antennas have been proposed to reduce the mutual coupling for UWB systems [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In [4][5][6][7][8], various decoupling structures have been inserted between two antenna elements to enhance wide band isolation.…”

“…A dual band-notched characteristic was created by using parasitic strips and slots on the radiator. In [13,14], Electromagnetic Band-Gap (EBG) structure was used to improve the isolation by blocking surface-waves propagation. The EBG structure with no metallic vias or vertical components was formed by etching two slots and adding two connecting bridges to a conventional uniplanar EBG unit-cell.…”

Abstract-In this paper, a compact multiple-input-multiple-output (MIMO) antenna is proposed for ultra wideband (UWB) communication. The UWB MIMO antenna consists of two identical monopole antenna elements with a comb-line structure on the ground plane to improve impedance matching and enhance isolation. Simulation and measurement have been analysed in terms of reflection coefficient, mutual coupling, dispersion diagram, radiation pattern, peak gain, efficiency and envelope correlation coefficient. Results show that the antenna has an impedance bandwidth larger than 3.1-10.6 GHz, mutual coupling between the two ports lower than −25 dB and envelope correlation coefficient less than 0.001 across the UWB band. The proposed antenna has a compact size of 26 × 31 mm 2 . All the measured and calculated results show that the proposed UWB MIMO antenna is a good candidate for UWB MIMO systems.
