ANTENNA ARRAYS : PERFORMANCE LIMITS AND GEOMETRY . optimization . by Peter Joseph Bevelacqua A Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy ARIZONA STATE UNIVERSITY. May 2008. ANTENNA ARRAYS : PERFORMANCE LIMITS AND GEOMETRY . optimization . by Peter Joseph Bevelacqua has been approved March 2008. Graduate Supervisory Committee: Constantine A. Balanis, Chair Joseph Palais Abbas Abbaspour-Tamijani James Aberle Cihan Tepedelenlioglu ACCEPTED BY THE GRADUATE COLLEGE. ABSTRACT. The radiation pattern of an ANTENNA array depends strongly on the weighting method and the GEOMETRY of the array. Selection of the weights has received extensive attention, primarily because the radiation pattern is a linear function of the weights. However, the array GEOMETRY has received relatively little attention even though it also strongly influences the radiation pattern.

optimization of an adaptive array based on the expected directions and power of the interference. This enables the optimization to perform superior on average, instead of for specific situations. An optimization problem is derived whose solution yields an optimal array for suppressing interference. Optimal planar arrays are presented for varying

to derivatives with respect to x, and where f is non-convex and multimodal. In these situations, Bayesian optimization is able to take advantage of the full information provided by the history of the optimization to make this search efficient. Fundamentally, Bayesian optimization is a sequential model-based approach to solving problem (1).
