Abstract (en)
The power division branching network having several branching nodes connected to output nodes (120a-120p), is determined, such that the ratio of power distributed to branches at branching nodes is minimized throughout the branching network. The optimal physical layout configuration of the branching network is determined. Microstrip lines are used in a tree structure. Independent claims are also included for the following: (1) method for providing passive beam forming network; and (2) system for generating passive beam forming network.
