Study of a Planar Topology ButlerMatrix for Printed Multibeam Antenna
Different structures of multiple-beam networks (beam-formers)
have been proposed, such as the Blass matrix , the Nolen , the
Rotman lens, and the Butler matrix [1]. The most important
beamforming networks used for multiple beams with lineaire
array are based on the Butler matrix. In this paper, new planar
8x8 Butler matrix the design were designed to form orthogonal
beamforming generates by 8 linear rectangular mirostrip antenna
array. The design procedure of matrix and its components,
hybrids and phase shifters are; prersented and descussed.
Keywords: Microstrip,Multibeam antennas, Butler matrix, printed antenna, phase shifters, couplers.
