Study of relative rotation cross dipole arrays with two pairs

In order to study the diverse polarization characteristics of non-identical cross dipole arrays, delta relative rotation cross dipole arrays with two pairs (delta-CAT) is proposed in this paper. It is proved that this kind of array has same linear dependent steering vectors distribution area (LDSVA) as two tripoles array when deltane0, delta effect is also quantitatively studied with Compton's results as reference, delta- CAT can include Compton's cross dipole array as special case and is expected to be a promising unit for diversely polarized arrays.
