Dual frequency ISM band butler matrix using planar coupler
A beamforming network with a multi-narrow-beam antenna array in dual frequency in ISM band (2.45GHz and 5.8GHz) is presented. The antenna array has four inputs and is excited by the Butler matrix feeding network to electronically steer the beams in desired directions, where the antenna array is capa...
