This paper describes the design and realization of a 4x4 Butler Matrix as a beam forming network along with 4 linear antenna arrays to obtain four steerable beams, operating at 2.4 GHz. The simulation results are obtained using HFSS software. Further the concept of multi-beam switching is discussed with an idea of suspended feed in between two matrices. Electronic scanning of antennas is used in a variety of applications and can be accomplished using Beam Forming Networks (BFNs). Butler Matrix is an NxN passive microwave network that consists of 'N' input and 'N' output independent ports. It is used as a feed to an array of antennas to generate a set of 'N' orthogonal beams, which scans the array generated beam.
