1. A phased array antenna comprising:

  • a plurality of planar panels each having opposing sides and top and bottom edges and forming an antenna face, wherein said planar panels are disposed circumferentially about a central axis, each panel connected to adjacent ones along the sides thereof and inclined toward the central axis from the bottom edge;

    a plurality of antenna elements positioned on each panel and forming an antenna array on each antenna face;

    a plurality of transmit/receive modules for generating and receiving signals, each transmit/receive module corresponding to a respective antenna element on an antenna array, wherein each transmit/receive module further comprises a phase shifter;

    means for connecting each of said transmit/receive modules to respective pluralities of said antenna elements within each array; and

    switch means for selectively controlling connection of said transmit/receive modules to respective antenna elements of one selected antenna array so that the transmit/receive modules are collectively connected to respective antenna elements of a selected antenna array at a selected time, such that the phase relationships among the antenna elements on an antenna array can be set, wherein said switch means and said plurality of antenna elements are phase matched to each other.
