New type high gain station antenna

There is an ever increasing demand for higher gain in omnidirectional fixed station antennas. A major factor in the pyramiding cost of these structures is the complexity of the feed system. Single feed point systems used in the past have had the disadvantage of low coupling between the driven element and the remotely located elements, resulting in highly tapered illumination and consequently lowered gain. A new principle for a radiating array has been developed which uses only one feed point but with improved aperture illumination. New elements called "suppressors" isolate the effective portions of the radiating conductor without a need for direct excitation. Results with a unit having 10 db gain at 460 MC are described.
