Abstract

A 3-D printed monolithic dielectric waveguide filter is presented in this paper. The proposed filter is constructed by a single piece of 3D printed dielectric puck with silver plated outer surface. To facilitate the fabrication of the monolithic dielectric filter, a lithography-based ceramic 3-D printing technology is employed. In this way, the mould required in conventional ceramic forming technologies is eliminated and the higher design freedom can be obtained. The detailed manufacturing parameters and post-processing methods are described. To demonstrate feasibility of the proposed solution, one prototype filter operating at 11.5 GHz with 850 MHz bandwidth is designed, fabricated, and measured. The measurement result shows reasonable agreement with the simulation.
