摘要：
A switched-beam antenna with reduced size and broadside beam based on the fractal Butler feeding network and fractal patch antenna array is proposed. The circuit sizes of the fractal-shaped branch-line couplers, 0 dB crossovers, and patch antennas, are 43.7, 50.1 and 74% smaller than their conventional counterparts, respectively. A four-beam prototype has been constructed. Measurement indicates that broadside beams with sidelobes below -10 dB are achieved.
