This final report describes an investigation of polarization agility for octave-bandwidth feed arrays in a 3-D dome antenna system. Both studies and experimental investigations were performed on this program. The studies include analyses of the polarization needs of 3-D dome antenna systems especially the feed array portion, and investigation of techniques for implementation, including octave-bandwidth, dual-polarization array elements and circuits for agile polarization. The experimental investigations have consisted of design, fabrication, and test of two small arrays of orthogonal notch elements and of a similar, linear-notch array. Both dual-polarization elements exhibit wide azimuth scan capability over at least an octave bandwidth. Beamwidths of the coincident-center notch element remain uniformly broad over the octave band. A bibliography is included which lists 7 references on polarization analysis, 23 references on elements, and 13 references on array performance. Author
