Abstract :
In this paper, four beam patterns generated by four identical planar antennas connected to a 4times4 Butler Matrix are presented. Each of the planar antennas consists of a 4times2 radiating array patch antenna which has the capability to produce a directional beam pattern. Butler Matrix 4 times 4 is chosen as a beamforming network and was designed to produce four independent beams in four different directions. The measurement patterns result achieved by this project is then compared with the theoretical calculation.
