ABSTRACT:
A phased array antenna includes a plurality of planar panels each having opposing sides and top and bottom edges and forming an antenna face. Each planar panel is disposed circumferentially about a central axis and is connected to adjacent panels along the sides thereof. Each panel is inclined toward the central axis from the bottom edge. A plurality of antenna elements are positioned on each panel. Each panel includes substantially the same number of antenna elements as adjacent panels and forms an antenna array on each antenna face. A plurality of transmit/receive modules generates and receives signals, and each transmit/receive module corresponds to a respective antenna element on an antenna array. Means connects each of the transmit/receive modules to respective pluralities of the antenna elements within each array. A switch collectively controls the connection of the 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.
