A shaped beam telemetry antenna for the ERS-1 satellite
Abstract
Design considerations and the approach used in developing a shaped beam telemetry antenna for the ERS-1 European synthetic aperture radar satellite are presented. The telemetry coverage from nadir to the horizon from a low orbit implies an unusual type of low gain antenna pattern. The 8 GHz antenna beam is required to be circular polarized and to peak sharply on a 62-deg off-axis annulus to provide compensation for range and atmospheric attenuation. The antenna design presented here comprises a center-fed reflector with a shaped profile and a specially designed compact feed horn.
