  • Stacked array antenna system
    Patent number: 6492959
    Abstract: A stacked array antenna system is presented having one or more antenna(s) as part of the supporting structure. This allows more than a single omni-directional antenna to be used with a minimum amount of azimuth pattern degradation. At least one antenna is actually part of the structure.
