MODERN ANTENNAS FOR SPACE COMMUNICATIONS
Abstract
Research trends in antenna design stress the probability that space communication and detection functions of future systems will depend on giant- aperture antennas operating at several hundreds of megacycles per second. The design principles and merits of large-acreage antennas such as spherical reflectors, paraboloidal reflectors, parabolic cylinder antennas, flat antenna arrays, and interferometers are reviewed, with particular attention to the new multiplate antenna design. The electronic scanning methods of antennas and arrays that are compared include some advanced designs for nonlinear antennas. New techniques of multibeam generation and antenna pattern optimization are suggested for improving the aperture efficiency and information-gathering capacity of future radio and radar space telescopes. To achieve these and other desirable improvements in the performance of space antennas, focal region research is important.
