  This letter presents an innovative design and implementation method for an
ultra-wideband dual-polarized conformal phased array. The performance of
single-layer continuous dipoles under bending conditions is evaluated through
characteristic mode analysis to understand the impact of curvature on
operational stability. This analysis provides design insights into the maximum
allowable curvature while maintaining stable dipole performance. Subsequently,
a single-layer metal radiation structure is designed as the array element, and
simulations indicate that it supports ultra-wideband operation with dual
polarizations. Using this element, an 8 * 8 ultra-wideband dual-polarized
cylindrical-conformal array (UDCA) is developed, demonstrating stable
performance even at a curvature radius as small as 100 mm. A physical prototype
is fabricated cost-effectively using novel manufacturing techniques that stack
a three-layer conformal substrate. Experimental result demonstrates that the
proposed UDCA with a 1.2{\lambda} curvature radius operates at 3.6~9.6 GHz
(90.9%) and achieves 60{\deg} wide-scanning in E-/H-planes, which provides a
practical and promising solution for conformal array applications.
