Abstract :
Antenna noise temperature is crucial to an optimal antenna design. In this paper a systematic evaluation of the antenna noise temperature for arbitrary antenna pointing angles and noise temperature profiles is presented. Its numerical implementation is discussed. Simulation results of a single offset reflector and an offset Gregorian antenna are used to validate the effectiveness in the antenna design phase.
