Abstract
This paper presents an effect of non-uniform plane wave on radiation pattern of a quasi-optical antenna-mixer array. Amplitude and phase excitation of the quasi-optical antenna-mixer array that takes non-uniform of plane wave illuminated on each element have been formulated. Simulation results show main beam squint and side lobe level error in term of number of elements. The results show examples of error of radiation patterns of the quasioptical antenna-mixer array fed by a non-uniform plane wave local oscillator. The result of this study provides the more accurate design of this antenna.
