Abstract :
A switched-beam antenna with a low sidelobe level based on a modified n*n Butler feeding network is proposed. This novel design only requires addition of 180(degree) power dividers in the Butler matrix part. A four-beam prototype is constructed. Measurement indicates that the sidelobe level is significantly reduced.
