1. An antenna system comprising:

  • an antenna array including a plurality of antenna elements for selective coupling to a radio frequency feed port, wherein at least two of the plurality of antenna elements generate an omnidirectional radiation pattern; and

    a plurality of electrically conductive shaping elements that change the omnidirectional radiation pattern generated by the at least two of the antenna elements, wherein at least one of the electrically conductive shaping elements includes switching elements that selectively couple and decouple corresponding electrically conductive elements to cause a change in the omnidirectional radiation pattern.
