ABSTRACT:
An antenna for radio wave communications. A first antenna section of planar array type is provided that operates at a first frequency and first polarization. A second antenna section of planar array type is provided that at a second frequency and second polarization. At least one of the first and second frequencies and first and second polarizations are substantially different. A table is provided that has a substantially planar surface and a central axis. The first and second antenna sections are mounted in parallel on planar surface and with respect to the central axis so that rotation of the table about its central axis mechanically scans the antenna with about the central axis. The first and said second antenna sections also are mounted with a separation so that the first antenna section does not substantially overshadow the second antenna section when the antenna is handling the radio wave communications.
