Abstract
This paper presents a brief overview of X -and$Ku$-band metallic 3-D printed antennas and passive waveguide components that are recently developed by the authors’ group, with an outlook to future innovative evolutions in structural design, additive manufacturing (AM), and post AM processing of similar types of passive waveguide components. The presented antennas and waveguides feature a monolithic integration of complex geometries in benefits of reduced fabrication cost, time, and labor, and are free of any assembly. The realization of high RF performance of these components demonstrates a high reliability of the utilized metallic AM and postprocessing.
