Abstract:

Analyses are presented for elements of a multiple plate antenna system capable of providing very large antenna aperture operation in a more economical fashion than present conventional designs. This report presents details of space transmission analyses, design for multiple element systems, and design and performance of a feed system specifically designed for the multiple plate antenna. In order to increase system bandwidth, multiple plate antenna aperture subdivided into smaller multiple plate antenna elements coherently added together by means of a space transmission system was investigated. Theoretical analyses and experimental data are presented for the space transmission system. Theoretical analyses were confirmed by space transmission experiments resulting in transfer efficiencies in excess of 22. A high performance feed was synthesized and designed for use with the multiple plate antenna at Strawberry Hill. The feed was developed to give an inverse taper aperture distribution in one plane and a cosine distribution in the orthogonal plane. Coverage from the feed system was designed to illuminate the multiple plate array in an optimum fashion. The synthesis procedure and details of design and performance of the feed system are described in the report.
