摘要：
A novel wideband dual-polarized conformal antenna array with low profile is presented by using dual characteristic modes (CMs) in this paper. First, by utilizing two set of orthogonal CMs that operate at the adjacent bands, a wide impedance bandwidth with dual- polarized operation is achieved in the antenna element design. Then, a columnar surface bending study is performed, leading to the development of a 4x5 cylindrical conformal array. The suggested conformal array exhibits a wide impedance bandwidth of 10.4%, a high polarized isolation of 15.1 dB and a low profile of 1.3mm (0.015 lambda), under 100-mm (1.16 lambda) radius of curvature. Such a low-profile wideband dual-polarized conformal antenna array provides an attractive option for contemporary and future communications systems.
