Reduction of side lobe level in non-uniform circular antenna arrays using the simulated annealing algorithm

This paper investigates the reduction of side lobe level in antenna arrays. Reduction of side lobe level in antenna arrays has some limitations including fixed width of the beam. We have modeled the side lobe level reduction as an optimization problem using simulated annealing technique for side lobe level reduction of a specific beam width. The advantage of this method compared with other methods is that it can get out...

Transformerless impedance matching networks for automotive power line communication

The automotive industry is constantly looking for ways of improving vehicles fuel economy, reliability, and reducing cost of manufacturing and maintenance. As a result, vehicle manufacturers have looked into power line communication (PLC) technology as a possible solution. However the nature of a vehicles power lines such as extremely low impedances, time varying channel characteristics, and noise make it difficult for...
