www.waves.utoronto.careal elements (via pattern multiplication) will increase the overall directivity of the array. 3 Di erent Array Excitations One of the biggest advantages of antenna arrays as that they allow many di erent array patterns to be synthesized. We have considered only one case so far, where each element is excited with an identical signal.

cslibrary.stanford.eduallocate arrays which seem "large enough" (e.g. the 100 in the scores example). Although convenient, this strategy has two disadvantages: (a) most of the time there are just 20 or 30 elements in the array and 70% of the space in the array really is wasted. (b) If the program ever needs to process more than 100 scores, the code breaks.
