Abstract
A dual-polarized antenna array for a one-dimensional (1D) active electronically steerable array (AESA) includes first and second arrays of open-ended waveguide elements interleaved with one another, each array including a plurality of corporate networks extending transverse to a scan plane SP and having a series of the elements spaced transversely of the scan plane, and wherein each of element is coupled to a respective corporate network by a waveguide twist and oriented oblique to the scan plane. The waveguide elements of one array are oriented orthogonal to the waveguide elements of the other array.
