NanoParticle Jetting NPJ is a new material jetting process that builds ceramic membranes
from zirconia nanoparticles embedded inside a liquid solvent that serves as a carrier. The …

In this paper, we investigate a shortened horn antenna with high gain that is enabled by a
3D-printed gradient index (GRIN) lens composed of high permittivity zirconia. The baseline …

Traditional high performance electronic substrates are currently fabricated with molds and
screens by stacking punched green ceramic tapes and selectively screen printing electrical …

In this paper, a review of the advances in dielectric resonator antennas (DRAs) in the last
few decades is presented, especially targeting ultra-wideband (UWB) with the …

In this paper, a rectangular dielectric resonator antenna (RDRA) with modified microstrip
feed is proposed. A pentagon-shaped aperture coupling with a bifurcated modified …

Additive manufacturing (AM) technologies have inspired extensive innovations in antennas
and wireless devices. AM processes can fabricate antennas that not only meet the …

Gradient-Index (GRIN) lenses provide simple feeding networks and a low cost for high gain
required in various fields such as military, mm-wave, 5G, and radar. Also, unlike a …

Antennas have been essential components for all aircraft and spacecraft since their
