Abstract :
The paper presents the analysis of the focal region field of an offset parabolic reflector antenna. The current induced on the reflector surface by an incident plane wave has been used to compute the field at the focal region. The analysis has been carried out for a reflector of diameter 1.8 meters by varying the f /d ratio and offset angle. The simulated results are presented. The validity of the analysis has been justified through comparison with the professional antenna design software.
