[ 1 ] - Optimization of Array Factor in Linear Arrays Using Modified Genetic Algorithm
The array factor (sidelobe level, SLL) of a linear array is optimized using modified continuous genetic algorithms in this work. The amplitudes and phases of the currents as well as the separation of the antennas are all taken as variables to be controlled. The results of the design using modified GA versions are compared with other methods. Two design problems were studied using several contin...
[ 2 ] - Nonlinear Analysis of a Power Amplifier inc C Band and Load Pull Technique Calculation USING VOLTERRA SERIES
In recent years, nonlinear circuit analysis techniques have been extensively investigated. One of the most important reasons is the application development of solid-state devices at microwave frequencies. Different methods have been used to analysis large signal behavior of these devices. In this paper load-pull curves (one of design requirement) are obtained using Volterra series. The main adv...
