Linear Arrays with arbitrarily distributed elements
TLDR
In this article, a linear array with general arbitrarily distributed elements is discussed and a matrix relationship is found between the elements of the array and its far-zone pattern, where the lower bound of the stored energy and the Q factor of the linear array are found.Abstract:
A linear array with general arbitrarily distributed elements is discussed. A matrix relationship is found between the elements of the array and its far-zone pattern. The lower bound of the stored energy and the Q factor of the array are found. A figure of merit for the array is defined.read more
