In this article, a compact coplanar waveguide (CPW) technique based ultra-wideband multiple-input-multiple-output (MIMO) antenna is proposed. The design is characterized by a broad impedance bandwidth starting from 3 GHz to 11 GHz (266%). The overall size of the MIMO design is 60 × 60 mm 2 (1.24 × 1.24 𝝀 𝒈 𝟐 @ 3 GHz) with a thickness of 1.6 mm. To make the design ultra-wideband, the proposed MIMO antenna design has four jug-shaped radiating elements. The design is printed on a FR-4 substrate (relative permittivity of 𝜀r = 4.4 and loss tangent of tan𝛿 = 0.025). The polarization diversity phenomenon is realized by placing four antenna elements orthogonally. This arrangement increases the isolation among the MIMO antenna elements. The simulated results of the ultra-wideband MIMO antenna are verified by measured results. The proposed MIMO antenna has a measured diversity gain greater than 9.98, envelope correlation coefficient (ECC) less than 0.02, and good MIMO performance where the isolation is more than -20dB between the elements. The group delay, channel capacity loss (CCL), and the total active reflection coefficient (TARC) multiplexing efficiency and mean effective gain results are also analyzed. The group delay is found to be less than 1.2ns, CCL values calculated to be less than 0.4 bits/sec/Hz, while the TARC is below -10dB for the whole operating spectrum. The proposed design is a perfect candidate for ultra-wideband wireless communication systems and portable devices.INDEX TERMS Multi-input-multi-output (MIMO), ultra-wideband, envelope correlation coefficient (ECC), channel capacity loss (CCL), group delay, total active reflection coefficient (TARC).

“…Human judgment of preferences making judgments of theses r compared crispy it is difficult to judge by values, therefore by ambiguity and inaccuracy to deal with classified issues fuzzy logic is essential. So, in ambiguous contexts with fuzzy logic to make better decisions there is a need to extend the DEMATEL system [13].When key criteria are identified, in order to use the DEMATEL system a second survey developed for management of sho chwan memorial hospital provided. Traditional multi-criteria unlike decision making techniques, generally the conditions are mutually independent consider that; this is for the DEMATEL system no need to assume but normality between criteria for decision makers to identify relationships also helps.…”

Techno economic means feasibility of project requirement and optimized technology means selection. Techno-economic means existing market and technology is an analysis of selection of technology in project design in demand capacity techno-economic max existing. Chamoli, uttarakhand, India electrical and cooking energy to meet the requirements, integrated renewable energy on the development of the system a techno-economic study has been carried out on paper. Locally available renewable energy resources and exploration capacity of area requirements an attempt has been made to assess. In this from analysis Decision making trial and evaluation laboratory (DEMATEL) complex system elements of the cause-and-effect chain a great one for identification considered proper. This is interdependence between factors assessing relationships and through visual structural modeling what matters deals with identifying. Alternative: air conditioner, color television, washing machine, water heater, electric cooker. Evaluation preference: air conditioner, color television, washing machine, water heater, electric cooker. The result it is seen that Air conditioner is got the first rank where as is the Water heater is having the lowest rank. As a result, the air conditioner gets the first rank, while the water heater gets the lowest rank.

“…A MIMO antenna with a four-port design is applied for wireless networking applications [ 25 ]. Furthermore, the reduction in size with ultra-wideband response is achieved with metamaterial loading in the MIMO antenna design [ 26 , 27 ]. Recently, a team of researchers has improved isolation with metamaterial loading in the MIMO antenna [ 28 ].…”

We proposed a novel approach based on a complementary split-ring resonator metamaterial in a two-port MIMO antenna, giving high gain, multiband results with miniature size. We have also analyzed a circular disk metasurface design. The designs are also defected using ground structure by reducing the width of the ground plane to 8 mm and etching all other parts of the ground plane. The electric length of the proposed design is 0.5λ × 0.35λ × 0.02λ. The design results are also investigated for a different variation of complementary split-ring resonator ring sizes. The inner and outer ring diameters are varied to find the optimized solution for enhanced output performance parameters. Good isolation is also achieved for both bands. The gain and directivity results are also presented. The results are compared for isolation, gain, structure size, and the number of ports. The compact, multiband, high gain and high isolation design can apply to WiMAX, WLAN, and satellite communication applications.
