Saddle-Shaped Pattern Synthesis by Element Rotation and Phase Optimization for Linear Dipole Array

The element rotation and phase optimization technique is utilized for synthesizing saddle-shaped pattern in this paper. As is known, the rotation of a dipole changes the co- and cross-polarized patterns in a given cut of the array pattern. Together with suitable phase control, it is feasible to synthesize shaped power patterns. An example of synthesizing a saddle-shaped pattern with reduced sidelobe level (SLL) and restrained cross-polarization level (XPL) is provided. The synthesized result validates the effectiveness of the proposed element rotation based technique.
