Generation of Sum and Difference Patterns of Linear Arrays Using Thinning

K. Kumar Naik, Vadlani Dinesh, K. Manoj Sanjay


Literatures are available on linear arrays with equal and unequal spacing. In this paper, the radiation patterns of linear arrays are numerically simulated using thinning. Thinning is a method by which the total number of active elements in a linear antenna array is reduced without causing major degradation in system performance. The present work is found to be useful in cost reduction while meeting some of the desired radiation characteristics and the sum and difference patterns are presented in results.
