Innovative Shielded High $Q$ Dielectric Resonator Made of Alumina by Layer-by-Layer Stereolithography

This letter presents a compact design of a shielded high unloaded Q dielectric resonator. The main interest of this work is the use of the three-dimensional stereolithography process to manufacture innovative ceramic radio frequency devices. Thus, a resonator, its support, and the surrounding cavity is manufactured in one part out of alumina by that process. The measured structure exhibits an unloaded Q of 3900 at 11.88GHz and is free of spurious modes over a 3-GHz range
