Abstract : The objective of this work was to develop theory for infinite arrays of microstrip elements, and incorporate that theory into the modeling of large finite arrays. The first topic, the effect of random positioning errors on the input impedance of an infinite array of printed dipoles, utilizes the infinite array solution to gain insight into the reduction or possible elimination of scan blindness for these arrays through the international introduction of random element positioning errors. Both planar and linear infinite random arrays are examined. In the second topic, the analysis and design of a microstrip reflectarray using patches of variable size, a rigorous solution to plane wave scattering from an infinite array of microstrip patches is performed. The data from this solution is then used to design a finite sized microstrip reflectarray. Several new topics in reflectarray analysis and design are examined, including the design of millimeter wave microstrip reflect-arrays.
