  Conformal phased arrays provide multiple degrees of freedom to the scan
angle, which is typically limited by antenna aperture in rigid arrays.
Silicon-based RF signal processing offers reliable, reconfigurable,
multi-functional, and compact control for conformal phased arrays that can be
used for on-the-move communication. While the lightweight, compactness, and
shape-changing properties of the conformal phased arrays are attractive, these
features result in dynamic deformation of the array during motion leading to
significant dynamic beam pointing errors. We propose a silicon-based, compact,
reconfigurable solution to self-correct these dynamic deformation-induced beam
pointing errors. Furthermore, additive printing is leveraged to enhance the
flexibility of the conformal phased arrays, as the printed conductive ink is
more flexible than bulk copper and can be easily deposited on flexible sheets
using different printing tools, providing an environmentally-friendly solution
for large-scale production. The inks such as conventional silver inks are
expensive and copper-based printable inks suffer from spontaneous metal
oxidation that alters trace impedance and degrades beamforming performance.
This work uses a low-cost molecular copper decomposition ink with reliable RF
properties at different temperature and strain to print the proposed
intelligent conformal phased array operating at 2.1 GHz. Proof-of-concept
prototype $2\times2$ array self-corrects the deformation induces beampointing
error with an error $<1.25^\circ$. The silicon based array processing part
occupying only 2.58 mm$^2$ area and 83 mW power per tile.
