Abstract :
A corporate-fed finite array of printed dipoles is analyzed. Mutual coupling between the array elements is accurately determined by accounting for higher-order coupling. An iterative analysis procedure is used to determine the effect of interaction between the array elements and the feed network. Feed loss is determined by comparison of the input and output power of the feed network, thereby including the effect of multiple reflections within the feed. Various small arrays have been investigated. As an example, results for a 4 by 4 element array are shown.<>
