Abstract :
A broadband Butler matrix with simple structure is presented, consisting of broad band rectangular patch hybrid couplers and novel broad band phase shifters using lambda/8 open and short stubs. Jumping genes evolutionary algorithm is employed to obtain the optimum design. It is measured to have a wide bandwidth of 35.6% centered at 3.65 GHz.
