Abstract	Slotted-waveguide antenna arrays find wide applications in communication and radar systems that require narrow beam or shaped-beam radiation patterns, especially when high power, light weight, and limited scanned areas are priorities. Placement of slots in waveguide plays a crucial role for shaping side lobes with desired values. An iterative procedure for calculating the placements of slot positions of slotted-waveguide array, which consists of an arbitrary number of slots, is presented in this paper. The offsets of the slots’ positions with respect to the waveguide centerline, which determine the side lobe level, were then obtained from well-known mathematical distributions like Chebyshev, Taylor, Binomial are presented. And the results are simulated in HFSS software.
