In this paper an investigation of the effects of the sequential rotation technique on the sum and difference patterns of monopulse radar antennas is presented. A LHCP polarized test antenna is designed and simulated and used to build linear arrays in different configurations. 10 cases for sum pattern with amplitude uniform and tapered amplitude distributions as well as 6 cases for difference pattern are compared in beam direction, beam width and axial ratio. The results show an influence on the pattern in particular for tapered sum patterns and difference patterns.
