Abstract

This paper presents the result of using omnidirectional antenna array on the switched beam antenna system. The 4times4 conventional Butler matrix has been used in this project as the beamforming network to provide four different values of the phase difference that coupled to antenna elements. By integrating the omnidirectional antenna array with 4times4 Butler matrix, this system has the capability to generate four different beams at four different directions with the coverage area of 360deg. Two types of beam can be generated by the system which are narrow beam and broader beam. The comparison between the measured and computed radiation pattern of the switched beam antenna also presented.
