Abstract |
|
An antenna array is composed of many elements whose excitation amplitude and phase can be individually adjusted to yield a desired pattern. Element failures cause sharp variations in the failed intensity across the array increasing the side lobe level of the power pattern. The defective elements of an antenna array need not be replaced. Reconfiguration of the amplitude and phase distributions of the remaining elements can partially compensate for the failed elements and thus reduce the side lobe level. Numerical results are presented to illustrate the effectiveness of the method. Genetic algorithm(GA) and real coded GA methods are robust optimization techniques based in the natural genetic for the search in complex spaces. These algorithms are computationally simple and can be easily improved. |
