Design and Performance Analysis of a Log Periodic Dipole Antenna with a Frequency Range of 1350 to 2690 MHz
Abstract: The introduction of broadband systems to communication and non-communication technologies has demanded the design of broadband antennas. RF antennas have relatively small bandwidth and poor directivity while the log periodic dipole antenna (LPDA) provides better directivity and gain with wide bandwidth. For a communication link and data transmission at higher rates, wider bandwidth is required with high gain and directivity. This necessitates designing a wideband antenna. In this paper, a …

A Critical Review on Semi-solid and Solid Lubricants for Industrial Applications
Abstract: Friction materials are very important for the safe moving of automobiles and the safety of people. As the pad slides against its match, the moving energy is turned into heat by the friction. As the vehicle's speed is lost as heat in the pads and rotors, the friction at the contact slows it down. Lubricants are compounds that are applied to moving parts to reduce friction and wear. Used primarily …
