Abstract:
High gain limited scan operation of phased array antennas is accomplished with microwave circuitry by appropriately coupling the array elements into sub-arrays and establishing a 90 degree out of phase relationship between even and odd mode power at the aperture of each array element. Even and odd mode power from the feed circuit of each element is coupled to the feed circuit of each nearest adjacent element to form three element overlap sub-arrays in each plane of scan.
