| Abstract: | In this paper, the application of overlapped subarray and its important role in beam forming network are introduced. The element characteristics of amplitudes and phases against frequency are also analyzed. It is pointed out that applying the branch line hybrid is a more convenient method to get "wide range of power division ratio" into realization for divider design. A new technique to reduce phase dispersion between subarray networks is proposed. Furthermore, the simulated and measured results are given. |
