STUDY OF SPECIAL BEAMSHAPING ANTENNAS.
Abstract
The report describes the progress during the past six months of a program to develop dielectric elements for use in lightweight, highly-transportable satellite communications antennas. A very large part of the effort during this period went into the publication of a Design Plan describing a four-element array of reflector antennas using Dielguide Cassegrain feeds. This array provides the gain of a conventional fifteen foot parabolic antenna with a total weight (array, pedestal, and trailer) of 663 pounds. A brief description of this array and its performance characteristics (taken from the Design Plan) are presented. Progress on the development of a Monopulse DIELGUIDE Cassegrain feed is reported. The thick-wall tube dielectric end-fire element has been investigated and found to have about 1-1/2 times the width and 1/4 the length of a dielectric rod antenna with the same gain. (Author)
