Abstract : An investigation and analytical study of antenna array elements is being carried out to determine the influence of an individual element of specific characteristics on the performance of an array and, on the basis of element performance, to present data which would assist the element designer in selecting the optimum element. A comprehensive literature survey will form part of the basis for the analytical study. The analytical investigation will analyze 49- to 215 element behavior and result in a determination of the 1000-element characteristics in the UHF (400MHz) through X-Band (10.5 CHz) range of frequencies. Other parameters and limits for the analytical investigation include: (1) Power handling capability (100 watts to 20 kilowatts); (2) Terminal impedance (25 ohms to 1000 ohms); (3) Signal bandwidths (from 10% to UHF to 5% at X-band); (4) Gain; (5) Polarization; (6) Beamwidth. For the literature search portion of the project (Phase I), a retrieval file system was designed and the file keysort cards for the system produced; several literature sources and contacts were established and are being used for data retrieval; and literature source data is being retrieved and entered on the Keysort cards as the program continues. Phase II is an analysis of array elements and performance patterns. (Author)
