A Novel Multi-Linear Polarization Reconfigurable Antenna Array

A novel multi-linear polarization (MLP) reconfigurable antenna array is introduced in this paper. By choosing an appropriate element polarization state distribution, the array can work in arbitrary desired linear polarization with side-lobe level (SLL) reduced pattern. In order to obtain the patterns of the array element in each polarization state, we use an approximation method. And a new optimization strategy is adopted to improve the accuracy of the synthesized patterns. Two numerical examples are given to verify the validity and correctness of the introduced scheme.
