The optimal design of Multiple-Input Multiple-Output (MIMO) antennas is significant for next-generation smartphone solutions with the appearance further communication. This paper describes design, simulation, and measurements a ten-element MIMO antenna n79 at 4.4–5.0 GHz, n102 5.925–6.425 n104 6.425–7.125 GHz ranges that will be implemented in today’s smartphones. proposed system has maximum dimension 158 mm × 60 use low-cost FR-4 as dielectric material. procedure carried out lot care to...
Non-linear electromagnetic waves obliquely propagating have been explored in multi-ion magnetized plasma, including resistance to motion, electro-polar charged ions, trapped electrons, and electro-negative heavy isotopes. For an unperturbed wave, the diversity of solitonic system is calculated using a direct algebraic scheme. The reductive perturbation bridge used as nonlinear KdV equations dispersion coefficients that rely on components plasma. We search out solutions for equation. As well,...
This work presents a unique two-element high-isolated orthogonally CPW-fed UWB Multiple Input Output (Ultra-wideband) antenna. The antenna is supported by the 52.8 × 29 mm2 FR-4 substrate, which has dielectric constant of 4.3 and thickness 1.6 mm. suggested MIMO reduces mutual coupling separating two single antennas that make up achieves voltage standing wave ratio (VSWR) less than more 86% radiation efficiency over whole range interest. antenna's performance assessed using both...
For automobile and aerospace engineers, implementing Hall currents thermal radiation in cooling systems helps increase the performance durability of an engine. In case solar energy systems, effectiveness heat exchangers collectors can be enhanced by best use hybrid nanofluids implementation a current, thermophoresis, Brownian motion, source/sink, time-dependent nanofluid flow over disk for Bayesian regularization ANN backpropagation algorithm. current physical model Cobalt ferrite CoFe2O4...
A two element Multiple Input Output UWB (Ultra-wide band) antenna is presented in this paper. The backed by the FR-4 substrate with a thickness of 1.6 mm and dielectric constant 4.3 covering an area 52.8 × 29 mm2. proposed MIMO consists single antennas stub placed between to reduce mutual coupling. achieves voltage standing wave ratio (VSWR) less than 2 more 86% radiation efficiency over whole band interest. Performance examined using both simulation experiment. design exhibits good...
Face recognition (FR) uses a passive approach to person authentication that avoids face-to-face contact. Among different FR techniques, most approaches place little emphasis on reducing powerful cryptography and instead concentrate increasing rates. In this paper, we have proposed the Hidden Markov Model (HMM) convolutional Neural Network (CNN) models for by using ORL Yale datasets. Facial images from given data sets are divided into 3 portions, 4 5 6 portions corresponding their respective...
A novel ground slot-based massive multiple-input multiple-output (MIMO) system with 14 elements for dual-band application of next-generation smartphones is developed. Every single antenna in the array placed on borders a smartphone’s PCB, operating within 3.55 GHz to 3.7 (n48) and 5.855 5.925 (n47) frequency bands. This study also further assesses performance this analytical results, which self-s-parameters are less than −6 dB each antenna, whereas isolation between components −10 dB. At...
