Includes bibliographical references (page 136). "The present study was initiated by the Communications Research Centre of the Department of Communications and of the Department of Supply and Services. Its basic aim was to investigate the feasibility of using antennas having beams of elliptical cross-section for CTS ground communications terminals. Such antennas may be used for communications experiments without ground terminal tracking. The elliptical cross-section beam is to provide the coverage of the rectangular angular region that represents the possible locations of the CTS relative to any of the ground terminal locations"--Introduction, page 1. gccst Satellites Canada.
