STUDY OF SPECIAL BEAMSHAPING ANTENNAS.
Abstract
Progress is reported on a program to develop dielectric elements for use in lightweight, highly-transportable satellite communications antennas. Dielectric elements investigated in order (1) to determine the dielectric element type most applicable to the transportable array problem and (2) to further reduce this element to useable hardware. The remaining portion of the program will consist primarily of the design, fabrication, and testing of an array model to demonstrate transportability features. The dielectric element investigations indicated that several types of dielectric elements are applicable. These elements were projected into possible array configurations which were evaluated and compared on the basis of transportability. As a result of these evaluations and comparisons, the reflector antenna with a Dielectric Cassegrain Feed has been found to be most applicable for use in highly-transportable systems and is more completely developed than the other dielectric element types. The Cylindrical Dielectric Antenna and the Dielectric-Loaded Reflector have been found to have some desirable characteristics for transportable applications. (Author)
