In this paper, a novel super-wideband multiple-input multiple-output (SWB-MIMO) antenna system with high isolation has been proposed, each antenna element consisting of a spade-shaped radiation Electrolytes patch, a defected ground structure (DGS) as well as a windmill-shaped decoupling structure.The elliptical slot etched on the radiation patch an
To suppress the deep fading of radio waves caused by the tunnel waveguide effect, this paper presents an optimized scheme for the spatial and polarization diversities of tunnel antennas.Through the correlation coefficient analysis of path loss curves obtained by antennas placed at different positions, the two antenna positions that generate path lo
Reservoir sensitivity is a parameter that is used to evaluate the degree of change in reservoir permeability under the influence of external fluids.Accurate evaluation of reservoir sensitivity is conducive to the optimization of fluid parameters during exploration and development.Taking the Wenchang Formation and Enping Formation of the Golf Bags P
Introduction: Research incorporating resilience, a concept featuring a positive outcome despite some type of stressor, has the potential to identify possibilities for promotion of the well-being of older people.This study aims to gain insight into the value and potential applications of resilience in both research and care practice from the perspec
