Abstract: Based on the field correlation theorem,the efficiency expres- sion of distorted reflector antenna is deduced,which is valid for the slowly varying surface distortions,and its relation to Rutz's formula is dis- cussed.It provides a more accurate expression of electromagnetic—structural relationship for reflector antenna design.
