Description
Summary:This report presents results of a study to determine the feasibility of constructing a very lightweight, highly-transportable, efficient, high-gain satellite communications antenna system subject to certain design specifications. In the first part of the report a survey is made of the most promising electrical (RF) and mechanical configurations. Eight basic antenna and five basic pedestals configurations were considered. A study was made of lightweight structural materials and also of tropospheric scatter communications antennas to determine the compatibility of this type of antenna to the SATCOM design. It was concluded that honey-comb aluminum and rigidized foam sandwich structures were preferable over lightweight, exotic materials for high-gain dishes and stainless steel was preferable for most type construction. As a result of this study, a preliminary antenna design was devised. Further consideration of this design lead to a final configuration which is considered to be an optimum design within the present state-of-the-art. (Author)
