A Fast LHCP/RHCP Reconfigurable Method With $\theta$-Axis Conjugate Symmetry Shaped Pattern Synthesis for Planar Rotated Antenna Array

In this letter, a fast reconfigurable left-hand circular polarization (LHCP)/right-hand circular polarization (RHCP) method is presented to synthesize $\theta$-axis conjugate symmetric shaped pattern with both sidelobe level (SLL) and cross-polarization level (XPL) control for planar rotated antenna arrays. The approximate conjugate symmetry property about $\theta$-axis of LHCP and RHCP patterns for a planar rotated antenna array is discussed and employed to reduce the complexity of synthesizing LHCP/RHCP reconfigurable shaped pattern computation. Finally, two representative numerical examples demonstrate the synthesis of reconfigurable LHCP/RHCP $\theta$-axis conjugate symmetric shaped patterns with SLL and XPL control, validating the effectiveness of the proposed method.
