- AbstractThis work presents a novel 3-D-printed triple-mode dielectric resonator for microwave filter applications. The design demonstrates the use of an odd number of periodic rings placed along a dielectric combline resonator to create a miniaturized filter structure capable of creating a quasielliptic triple-mode filter response. A new approach suitable for 3-D-printing of the periodic rings is presented using support structures that take the form of struts. The resonator is fabricated using alumina with lithography-based ceramic manufacturing and housed in a compact single-cavity structure. The filter is designed for operation with a center frequency of 10.78 GHz, fractional bandwidth (FBW) of 2.13%, and a measured quality factor of approximately 1700.
