The unattended earth terminal multiple-beam torus antenna
Abstract
This paper deals first with the electrical characteristics of the front-fed conical torus antenna as developed analytically and verified by scale-model antenna measurements. The unattended earth terminal multiple-beam torus antenna (UET MBTA) design and measurements are then discussed. Noise temperature performance is estimated. Next, the corrugated horn used to feed the MBTA is briefly reviewed. The orthomode transducer and polarizer requirements, design, and performance are then developed. The beam steering mechanism is described in detail. This is followed by a discussion of the structural requirements, analysis, and design. Finally, the erection and checkout of the structure are described.
