  • Patent number: 5506589
    Abstract: An array system with radiating elements and a wideband monopulse power divider network with dual channel input ports and multiple output ports. Each input channel of the network excites a uniquely different RF amplitude and phase distribution out of each of the corresponding "n" output ports. All ports are matched and isolated from each other across a wide instantaneous frequency. Also the RF power distribution will track in amplitude and phase across a wide frequency band. This is achieved through a special arrangement of air-stripline matched power dividers, attenuator, phase shifters, and Magic-Tee couplers. The output ports of the network can be connected directly to the radiating elements or to partitioned feed circuits which are in turn connected to sub-sets of the radiating elements.
