Abstract : The report describes the effort expended during the first quarter of the Engineering Change 'A' portion of the Electronically Steerable Array Program to design and build a high gain, electronically steerable, millimeter antenna system. Design goals for the breadboard model antenna system were formulated during this period, preparations were made for evaluating cubic and hexagonal ferrites for scanning tests and a detailed analysis was made of a proposed hybrid antenna system employing ferrites and a scattering mechanism. The results of this analysis, however, indicate that the hybrid system selected for analysis will not meet all the performance goals of the system so that future design work will be concentrated on ferrite scanner techniques.
