Rotman lens, true time delay beam forming network, is a promising candidate for many radar and antenna systems producing large scan angle, multi-beam forming and wide band operations. Very often, accurate analysis of Rotman lens is necessary in studying its performance prior to the fabrication. Recently, researchers have analyzed Rotman Lens using various numerical techniques except method of moments (MoM). In this paper, a C-band Rotman lens simulation is conducted using MoM with planar Green’s function in FEKO. The results are validated with the measured data. Prominent matches between FEKO and the measurements are observed.
