Three-element broadband narrow beam without side lobes array antenna

What is it about?

Array antenna with 3 Luneburg lenses. This array concentrates the energy only in one direction. The array is not parasitic radiation (side lobes of diagram). The Luneburg lenses are broadband lens antennas. The signal processing uses original formulas. That leads to high and constant selectivity of the array antenna main beam in broad band frequency range.
