In the design procedure of the reflect array antennas, the fast analysis of the aperture efficiency and radiation patterns is necessary before manufacture to forecast the antennas performance proximately. The fast calculation of the aperture efficiency and radiation patterns of reflects array antennas are presented in this paper. A more general approach is introduced to calculate the spillover efficiency of a reflect array. Meanwhile, the taper efficiency of the reflect-array is calculated with a unified set of equations.
