In this presentation we demonstrate the ability to print RF radiating structures and feed networks with multi-layer structures which have been designed and optimized for printing. A study is carried out to determine the performance of conductive inks at Ku-band frequencies as well as the effect of depositing these inks on printed substrates. Using this data, a model for printed conductor performance is developed and then applied to multi-layer radiating and feed networks. Embedded antenna arrays are fabricated and measured showing good agreement between the model and fabricated parts. Novel interfaces are then designed, optimized, and printed for connecting to standard connectors, such as SMP/SMA. Grading techniques are also used to create a 3D Luneburg lens which is structurally robust as well low loss.
