Abstract
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 capable of pointing to desired targets |1). Beam forming and pointing control are carried out mainly by changing the phase of the feeding signal, in what is referred to as a phased-array-fed system resulting multiple narrow beams in different directions with high gain
