| Abstract Scope |
Antennas are essential components of all radio equipment that radiate/transmit and receive energy as electromagnetic waves. Next-generation wireless communications demand lightweight, low-profile, and high-performance antennas that require co-evolution in both design and manufacturing of antennas. Here we report the design and printing of previously impossible ultra-lightweight antennas via charge programmed multi-material additive manufacturing. We achieve this via tailoring the charge programmability of photopolymer to enable selective metalization of 3D conductive materials. These antennas are comprised of a network of interpenetrating metal and dielectric phase-shifting 3D unit cell arrays, which enable 3D electronic topologies with significantly less material (over 90% weight reduction) compared to standard antenna designs. We demonstrate the design and printing of full antenna systems comprised of a feed source, a 19 GHz circular polarized transmitarray with 20 cm aperture. Our measurement results obtained with the spherical near-field measurement system reveal excellent agreement with the simulated radiation patterns. |
