A power dividing horn for the offset parabolic cylindrical reflector antenna (OPCRA) is proposed. When the horns constitute an array, the grating lobes can be suppressed to －28 dB because of the improved aperture field. Compared with the OPCRA using conventional pyramidal horn array feed, the aperture efficiency of the OPCRA fed with power dividing horn array, which is simulated by FEKO, is improved from 68% to 80%. And the gain of the OPCRA can also be increased by 0.7 dB．
