Advanced 4-Element UWB-MIMO Antenna Design: Achieving High Isolation and Multi-Band Rejection for Advanced Wireless Applications
Abstract: In this study, we present the design, fabrication, and analysis of a step-by-step Ultra-Wideband (UWB) Multi-Input Multi-Output (MIMO) antenna operating from 3 to 14 GHz. The antenna consists of four elements, each characterized by high isolation and equipped with four band-rejection features. These elements are implemented on a Rogers substrate with εr=3. Each antenna element is a modified rectangular patch, incorporating partial ground etching to achieve wider bandwidth. Two sets …

Experimental Investigation and Surface Morphology Study on Areca Fiber Composite Material
Abstract: Composites manufactured from areca fibers had their characteristics assessed in recent research. Shape and size were determined by cutting the stem. It takes six months to dry the fibers once they are taken from the tree stem. Because pectin, cellulose, hemicellulose, and lignin make up the bulk of it. It has great regeneration capacity and is a resource material made of wood fibers. The untreated and chemically treated fibers are …

Optimization and Structural Integrity of Truck Chassis Using Finite Element Analysis
Abstract: The chassis of a truck is a crucial component, and it acts as a framework for the body and other components of the truck. It must also be strong enough to withstand pressures like shock, twisting, vibration, and more. When building a chassis, having enough bending stiffness for better handling characteristics is just as important as strength. Deflection, maximum stress, and maximum equilateral stress are crucial design factors for the …

In Silico Exploration of Podophyllum Hexandrum-Derived Phytocompounds as Potential Therapeutics Against Small Cell Lung Cancer (SCLC): A Molecular Docking Approach
Abstract: Small Cell Lung Cancer (SCLC) is a fast-growing and aggressive type of lung cancer that spreads quickly strongly associated with smoking. It is characterized by symptoms, such as persistent cough, breathing difficulties, or hoarseness, though it can sometimes be asymptomatic which makes early detection challenging. The tumor suppressor gene TP53 is critical in regulating the cell cycle and preventing uncontrolled cell division. Mutations in TP53 result in the loss of …
